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 ?

  • For bsim4 you have these parameters (from spectre -h bsim4)

    444 tnoia=1.5 Coefficient of channel-length dependence of total channel thermal noise.
    445 tnoib=3.5 Coefficient of channel-length dependence of total channel thermal noise.
    446 tnoic=0.0 Thermal noise parameter.
    447 rnoia=0.577 Thermal noise coefficient.
    448 rnoib=0.5164 Thermal noise coefficient.
    449 rnoic=0.395 Thermal noise coefficient

    For bsim3v3, you have:

    248 gamma=2.0/3.0 Thermal noise coefficient.
    250 gdsnoi=1.0 Channel thermal noise coefficient for 49 noise.

    I have no idea whether messing with these parameters will do what you want. Suck it and see, I guess!

    Regards,

    Andrew.
