Noise Analysis of OPAMP

In this tutorial, I am showing how to do noise analysis of an OPAMP or any other circuit in general.
I also try to explain some utilities in cadence which can help you to optimize your design for low noise specifications

Sir I am working on CMOS double tail comparator. Through this way can I find out input and output noise for the entire comparator design?

hello, how choose the value of dc source from gates? (1.8V , 0.8V , 0.4V)
