yes, you can run pss and pnoise. more example you can find the openbook of cadence: spectrerf
Hi there Do you know where I can find noise model flag, noimod, in my technology mode file (*.scs) for spectre ? Since I would like to whether noimod=1 or others in order to check my Pnoise simulation results for flicker noise. Right now, I found I couldn't see the flicker noise for (...)
Quote: Analog_starter Hi, how can I do SNR simulation by Hspice ?? BTW, in spectre can I add .vec file into it ?? Using .fft in hspice can do fft simulation and get THD. And .vec file can be used too. But for SNR, i don't kown how to simulate it.
I have a question. The simulation software I use is spectre RF. If I want to add a noise current (say 4pA/ sqrt Hz) to the current source (1mA), How do I do this in simulation ? I don't know the answer, but it should not be paralleling a resistor because the resistance of the current source should be infinity. (...)
Why not try spectre of Cadence, the new version of spectre even display jitter directly in Pnoise simulation
Dear All : Does Anyone know how to simulate the input reference noise using hspice or spectre-RF , Thanks
Maybe the following paper helps you, even it is written for spectre. However, some of this ideas can be taken for hspice, pspice , ..., i think.

Hello There; I am wondering why I get a 2 dB difference when I simulate IIP3 using the PSS/PAC method in spectreRF and the method of two tone IIP3 simulation using transient analysis with same input power prf (which is in the linear range of the front -end). From the manual, seems spectreRf also use IIp3=Prf+deltaIM3/2 to get IIp3 (...)
By definition noise figure calculations in spectre are SSB. This is because spectre simulates the output noise and he doesn't know whether it comes only from one sideband or from both, and then it divide it by gain to calculate NF. But gain (transfer function in the tab, if I well remember) is calculated with a CW only in (...)
