Hi,
I do have one general and three specific questions concerning operating-point parameters (especially for BSIM4).
General question:
1. The operating-point parameters are not defined by the BSIM4 model, but are specific to the simulator used (Spectre, HSpice, Eldo), correct ?
This is why I find the operating point parameters documented in the Spectre documentation only and not in the BSIM4 manual, right ?
Specific questions to operating point parameters:
2. What is the difference between OP "vdsat" and "vdss" (I don't find any explanation in the latest spectre documentation v18.10 and the values after simulation seem to be the same) ?
3. What is the difference between OP "betaeff" and "beff" (I don't find any explanation in the latest spectre documentation v18.10 and the values after simulation differ) ?
4. What is OP "self_gain" ( I assume it is the intrinsic gain of gm*rout, but did not find documentation for it) ?
