Hi, Thank you for your reply. Does Rds(ON) depends on device geometry? Could you please explain me? Regards.

Click to expand... Hi, I have checked with TSMC180nm process technology file (rf018.scs). Nowhere, I have found a device parameter called rds. Could you please guide me where where can I get the value of rds(on) for nmos2v cell of 180nm technology? Thank you. With regards.
