Hi,
thanks for the reply.
Quote:PSTB is no more than PAC of sideband=0.
I'll try PAC tomorrow. thanks
Quote:Where do you insert probe ?
I'm using an op-amp based TIA, so I inserted the probe at the input of the opamp (connected to the gate of the input transistor).
I expected there to be some difference between stb and pstb analysis, but obviously not that much. BTW in order for PAC analysis to run correctly, I had to change the parameter "version" in the BSIM model file from "version=3.3" to "version=3.2". Could the problem have something to do with that?
thanks,
Aaron
