what is the value of channel length modulation constant in 90nm in cadence

[shrikant_joshi7]

how to calculate channel length modulation constant lambda in cadence gpdk90nm.
i calculated it by gds/id and also by pclm parameter( but the values are 1.5488 and 1 which seems to be very large) as compared to 500nm technology which is given in RAJAVI's book.
if u have calculated plz tell me.

You can plot Id vs. Vds and extrapolate to the crossing point with the horizontal axis. But this is a lost battle - for sub-100nm technologies, ro varies all-over the place. You'll most probably get different lambda values for different Vgs. Not to mention that if well modeled, the ro will vary also with the Vds.
