How to disable the thermal noise but not flicker noise in SpectreRF

RFStuff

Dear all,

Is there any way to disable the thermal noise but not flicker noise in SpectreRF ?

  • Other than you looking at an old version of the manuals, the main problem is that the PDF is out of sync with the simulator. I was using "spectre -h bsim3v3" instead:

    UNIX> spectre -h bsim3v3 | grep -i noise
    13 isnoisy=yes Should device generate noise. Possible values are no
    Noise model parameters:
    237 noimod=1 Noise model selector.
    238 kf=0 Flicker (1/f) noise coefficient.
    239 af=1 Flicker (1/f) noise exponent.
    240 ef=1 Flicker (1/f) noise frequency exponent.
    244 noid=2e14 flicker noise subthreshold-above threshold transition
    245 wnoi=1e-5 m Channel width at which noise parameters were
    247 flkmod=0 Flicker noise model (0 for Ids based model, 1 for gm
    248 gamma=2.0/3.0 Thermal noise coefficient.
    249 nlev=2.0 49 noise selector.
    250 gdsnoi=1.0 Channel thermal noise coefficient for 49 noise.
    251 lintnoi=0 m Lint offset for noise calculation.
