  1 | Flicker Noise Formulations in Compact Models
  2 | ============================================
  3 | 
  4 | :Author: Geoffrey Coram, Colin McAndrew, Kiran Gullapalli and Ken Kundert
  5 | :Version: 1.2.0
  6 | :Released: 2020-11-13
  7 | 
  8 | Includes a resistor model that demonstrates how to properly model flicker noise 
  9 | in Verilog-A as described in:
 10 | 
 11 |   | `Flicker Noise Formulations in Compact Models <https://kenkundert.com/docs/tcad20-flicker-noise.pdf>`_;
 12 |   | G. J. Coram, C. C. McAndrew, K. K. Gullapalli, and K. S. Kundert;
 13 |   | IEEE Transactions on CAD, vol. 39, no. 10, October 2020.
 14 | 
 15 | Also included are two circuits. The first is a simple test circuit for the 
 16 | resistor model.  Here Rva is the Verilog-A model and Rref is the resistor model 
 17 | that is built-in to Spectre.

 22 | 
 23 | The second is a circuit that tests the implementation of flicker noise in the 
 24 | built-in BSIM4 model.

 29 | 
 30 | If you have a recent version of Spectre, you can simulate the circuits directly 
 31 | and view the results in your favorite waveform viewer.
 32 | 
 33 | If you have Python 3.6 or later, you can also run the simulation scripts, which
 34 | re-generate the netlists, run the simulations (in Spectre), and plot the 
 35 | results.
 36 | 
 37 | To install the script dependencies, run::
 38 | 
 39 |    pip install -r requirements
 40 | 
 41 | Then simply run::
 42 | 
 43 |    ./runPnoise
 44 | 
 45 | or::
 46 | 
 47 |    ./runBSIM
 48 | 
 49 | These run a simulation and plot the results. You have the -v option and the 
 50 | logfile (.runPnoise.log or .runBSIM.log) to help you out if you run into any 
 51 | problems.
 52 | 
 53 | You can also run a simulation of the broken resistor model::
 54 | 
 55 |   ./runPnoise --broken
 56 | 
 57 | You can view the signal and waveforms with::
 58 | 
 59 |    > list-psf -f pnoise.raw/pnoise.pnoise -l
 60 |    > show-psf out
 61 | 
 62 | My rather old version of Spectre (15.1.0) generated the following results:
 63 | 
 64 | 
 65 | Resistor
 66 | --------
 67 | 
 68 | .. image:: figures/resistor.svg
 69 |     :width: 600px
 70 |     :align: center
 71 | 
 72 | The above shows the flicker noise produced by Spectre's built-in resistor 
 73 | (*RESref*) and the proposed Verilog-A model (*RESva*). In this case the flicker 
 74 | noise of the built-in resistor model was implemented correctly and both agree.
 75 | 
 76 | Flicker noise in a resistor is a variation or a flickering in the value of the 
 77 | resistance over time. The variation has a *1/f* power spectrum and is completely 
 78 | bias independent; it is not affected by the applied signal at all.  You can 
 79 | observe the flickering by applying a DC bias voltage to the resistor.  The 
 80 | result will be a noise in the current with a *1/f* spectrum.  In this circuit we 
 81 | instead apply a sinusoidal voltage with a frequency of 131kHz and no DC 
 82 | component to observe the flickering.  This results in the same *1/f* 
 83 | characteristic in the noise, but now mixed up to 131kHz as shown in the figure.
 84 | 
 85 | 
 86 | Broken Resistor
 87 | ---------------
 88 | 
 89 | .. image:: figures/resistor-broken.svg
 90 |     :width: 600px
 91 |     :align: center
 92 | 
 93 | The above shows the flicker noise produced by Spectre's built-in resistor 
 94 | (*RESref*) and the traditional Verilog-A model (*RESva*). In this case the 
 95 | flicker noise of the Verilog-A model is incorrect and the two models 
 96 | disagree.
 97 | 
 98 | In this case the simulator discards the sign of the sinusoid when performing the 
 99 | noise calculation. As such, it appears to the resistor that the applied test 
100 | signal is not a pure tone sinusoid, but rather a fully rectified sinusoid. So 
101 | rather than have a single spectral component at 131kHz, it has components at 
102 | each of the even harmonics of 131kHz, meaning it has components at DC, and 
103 | 262kHz, 524kHz, etc.  The result is that the *1/f* spectrum from the flicker 
104 | noise is replicated and shifted up by each harmonic, meaning that there are 
105 | peaks at each of the harmonics of the rectified sine wave.  The peaks are 
106 | equally spaced in frequency, but they appear to be getting closer together at 
107 | higher frequencies because the *x*-axis uses logarithmic scaling.
108 | 
109 | This problem is further illustrated in the graphs below. In this case both the 
110 | built-in resistor and the broken version of the Verilog-A resistor are driven 
111 | with a 1Vp sinusoid where the DC offset is swept from 1V to –1V. In the first 
112 | and last graphs, the offset is 1V and –1V, so the current through the resistors 
113 | never change sign.  They are either always positive or always negative. In these 
114 | cases, discarding of the sign is of no consequence and the noise computed for 
115 | the two resistors agree.  There is a peak at *f* = 0 because of the DC component 
116 | of the modulation signal, and a peak at *f* = *f₀*, which is the drive 
117 | frequency.  In the results for the 0 V offset, the built-in resistor only shows 
118 | a peak at *f₀*, the drive frequency, whereas the broken resistor shows peaks at 
119 | each of the even harmonics of the drive signal because the sign of the drive 
120 | signal is lost.
121 |

126 | 
127 | BSIM
128 | ----
129 | 
130 | .. image:: figures/bsim.svg
131 |     :width: 600px
132 | 
133 | The above shows two different flicker noise models implemented in the built-in 
134 | BSIM4 model in Spectre.  *fnoimod=1* was implemented correctly while *fnoimod=0* 
135 | was not.
136 | 
137 | A good first order model for flicker noise in MOSFETs is a bias independent 
138 | variation in the threshold voltage.  This variation tends to modulate the 
139 | current passing through the channel. If the channel current is DC you end up 
140 | with simple *1/f* noise. However, if the channel current is sinusoidal, the 
141 | flicker noise is up-converted to the frequency of the sinuosoid, as seen with 
142 | *fnoimod* = 1.  However, the implementation of *fnoimod* = 0 discards the sign 
143 | of the sinusoid when doing the noise calculation, and so we again see peaks at 
144 | each of the even harmonics of the test signal.

  4 | Simulate BSIM4 Flicker Noise with PNoise Analysis

  6 | Usage:
  7 |     runBSIM [options]
  8 | 
  9 | Options:
 10 |     -v, --verbose  turn on verbose mode
 11 | 
 12 | Run a PNoise simulation on BSIM4 transistors, testing the implementation
 13 | of the flicker noise model (selected by model parameter fnoimod). In
 14 | certain simulators at the time this example was created, the noise spectra
 15 | are qualitatively different: the location of the spikes differs, depending
 16 | on fnoimod.
 17 | 
 18 | For fnoimod=1, the simulation results are correct: the flicker noise is
 19 | up-converted to be centered around f0. The drain-source voltage is small,
 20 | so that the transistor is in the linear region. For fnoimod=0, the noise
 21 | spectrum differs: the spikes are at different locations, whereas we 
 22 | expect only different amplitudes.
 23 | 
 24 | The simulation results were reported in the paper "Flicker Noise Formulations
 25 | in Verilog-A Compact Models" by G. J. Coram, C. C. McAndrew, K. K. Gullapalli,
 26 | and K. S. Kundert; IEEE Transactions on CAD, vol. 39, no. 10, October 2020.

 29 | ampl in this program.

  9 | Options:
 10 |     -v, --verbose  turn on verbose mode
 11 |     -b, --broken   use the broken version of the model
 12 | 
 13 | Run a PNoise simulation on Verilog-A and built-in resistor models exhibiting
 14 | flicker noise driven by a sinusoidal excitation.  The model "res_va" in the 
 15 | resistor.va file is used, as is the built-in spectre resistor model.
 16 | 
 17 | The frequency and amplitude of the excitation are set by the variables f0 and
 18 | ampl in this program.
 19 | 
 20 | The simulation results were reported in the paper "Flicker Noise Formulations
 21 | in Verilog-A Compact Models" by G. J. Coram, C. C. McAndrew, K. K. Gullapalli,
 22 | and K. S. Kundert; IEEE Transactions on CAD, vol. 39, no. 10, October 2020.
 23 | 
 24 | The file resistor.va preserves the sign of the modulation.  The simulation
 25 | results are correct with the flicker noise being up-converted to f0.  With the
 26 | command-line option --broken, the incorrect implementation of flicker noise,
 27 | found in broken.va, is used instead. Here the absolute value causes loss of the
 28 | sign of the modulation and you get the incorrect results where the flicker noise
 29 | is upconverted to 2*f0 and its harmonics. This is shown in Fig. 2 in the above
 30 | paper.

  4 | Simulate Resistor Flicker Noise with PNoise Analysis
  5 | 
  6 | Usage:
  7 |     runPnoise [options]
  8 | 
  9 | Options:
 10 |     -b, --broken              use the broken version of the model
 11 |     -s <file>, --svg <file>   produce plot as SVG file rather than display it
 12 |     -v, --verbose             turn on verbose mode
 13 | 
 14 | Run a PNoise simulation on Verilog-A and built-in resistor models exhibiting
 15 | flicker noise driven by a sinusoidal excitation.  The model "res_va" in the 
 16 | resistor.va file is used, as is the built-in spectre resistor model.
 17 | 
 18 | The frequency and amplitude of the excitation are set by the variables f0 and
 19 | ampl in this program.
 20 | 
 21 | The simulation results were reported in the paper "Flicker Noise Formulations
 22 | in Verilog-A Compact Models" by G. J. Coram, C. C. McAndrew, K. K. Gullapalli,
 23 | and K. S. Kundert; IEEE Transactions on CAD, vol. 39, no. 10, October 2020.
 24 | 
 25 | The file resistor.va preserves the sign of the modulation.  The simulation
 26 | results are correct with the flicker noise being up-converted to f0.  With the
 27 | command-line option --broken, the incorrect implementation of flicker noise,
 28 | found in broken.va, is used instead. Here the absolute value causes loss of the
 29 | sign of the modulation and you get the incorrect results where the flicker noise
 30 | is upconverted to 2*f0 and its harmonics. This is shown in Fig. 2 in the above
 31 | paper.
 32 | 
 33 | Simulation Parameters:
 34 |     f0 (fₒ) = 2**17 "Hz"            — frequency of the modulating sinusoid
 35 |     ampl = 100mV                    — amplitude of the modulating sinusoid
 36 |     ptsPerCycle = 64                — number of desired points per cycle
 37 |     cycles = 2048*16                — total number of cycles
 38 |     T = 1.0/f0 "s"                  — period of one cycle
 39 |     dt = T/ptsPerCycle "s"          — (desired) time between transient simulation samples
 40 |     tstop = T*cycles "s"            — stop time for transient simulation
 41 |     fmin = 1.0*int(1.0/tstop) "Hz"  — minimum frequency for analysis
 42 |     fmax = f0*ptsPerCycle/2 "Hz"    — maximum frequency for analysis
 43 |     ptsPerDec = 2000                — number of frequency points per decade
 44 |                                     — for the noise analysis
 45 | """
 46 | # These simulation parameters are unusual because simulations involving
 47 | # transient noise were run during the course of writing the paper, and the
 48 | # values used in both the PNoise and transient noise simulations were chosen to
 49 | # be consistent.  Many of the values defined above are not needed with a simple
 50 | # PNoise analysis, and their values need not be so carefully chosen.
