PCLM parameter in BSIM3.2 model

bsim3 pclm channel length modulation

Hi,
I have a question on the chanel length modulation parameter, i.e., PCLM. Can anyone pls. tell me if this parameter is the lambda in the drain current equation to account for the channel length modulation effect?

I have this question is because I set pclm equal and not equal zero, I found not much drain current descrepancy for a current mirror, alough I see their obvious different Vds.


Thanks in advance

what is pclm in bsim3 model

Typically this parameter is extracted for output resistance modeling and should not
be used for any other one. Effects seen from varying this parameter should be minor
due to vds variation.

Hope that will help.
