I am designing an DIFFERENTIAL OPAMP in Cadence and would like to know if there are any tutorials that show how to measure the performance (different dc and ac parameters like gain, offset voltage, offset, bandwidth, distortion, etc.) of the OPAMP in Spectre?
Iref depends on your required bandwidth. cmref usually is (vdd-vss)/2 . Read any book on Analog Design (e.g. Allen/Holberg, Baker, Binkley, Gray/Meyer, Razavi) ... just to name a few.

Is there another tutorial to help understand how to plot all the analyses?
