0.25 um cmos transistor help needed.!!!

[umairmian2002]

i want to find the equivalent RC circuit of static cmos 4 input and gate

my requirements are

nmos: W/L = 4/2
pmos: W/L =8/2

how can i calculate the values of R and C values please tell me the formulas and their parmeter values for 0.25 um technology.

i want to values of R and C and also how you calculate them.
what i have to do is make RC equivalent of static cmos and simulate in Orcad 9.2 and then reduce the delay of critical path and draw its layout in Microwind. PLease help me that how can i do all this. specially R and C values...

thanks

Pls try Calibre xRC to extract it. Of course you must have command file from the foundry.

or you can check the process file.

find the sqare res and the gate cap values, then run a few calculations
