Comparison of Gain calculation of Common Source Amplifier with Simulation

[haideruet]

Is there any way for in hand calculation of gain of very simple CS stage amplifier (e.g from Razavi book),
which can be comparable with Simulation results in cadence.

Depends on the process used, and its simulation models. In any case use L » Lmin (to get rid of CLM limitations), and see that you operate the transistor(s) at least in moderate, better in strong inversion mode if you use low level sim. models.
