2 Don t let the computer think for you In today s analog design, simulation of circuits is essential because the behavior of shortchannel MOSFETs cannot be predicted accurately by hand calculations. Nonetheless, if the designer avoids a simple and intuitive analysis of the circuits and hence skips the task of gaining insight, then he/she cannot interpret the simulation results intelligently. For this reason, we say, Don t let the computer think for you.  Behzad Razavi

45 Common Mode Feedback Why is CMFB circuit needed? Due to TR mismatch, TRs may not be in saturation region at operating point. DM Gain decreases and CM gain increases Since output CM level is sensitive to device properties and mismatches, it cannot be stabilized by means of differential feedback.
