bsim3 pclm
The channel length modulation coefficient lambda usually has a typical value between 0.001V-1 and 0.1V-1 for level 1 transistors.
Why in Bsim3 models, instead of lambda you have 'pclm' to represent channel length modulation, why does it have no units, and why can the value exceed 1.
Just curious about this because im following razavi's analog ic design book and he uses the level 1 values of lambda to calculate gain of opamps.
When i plug in my pclm values (which are 1.1 at the moment) into the same equations he uses, my gain is much much less. Im just wondering if im doing anything wrong.
Thanks
