Can someone recommend a step by step guide covering basics like sizing the differential pairs, choosing tail current, second stage to first stage sizing ratios, etc etc?

I have used the universal testbench with two diffamps in series in order to measure gain, CMRR, but could use a step by step guide to go along with the unviersal testbench.

I am familiar with how to verify 2 stage diffamps and folded cascode regulators.

But need to learn more about ground up design steps.

Any suggestions are appreciated?
Thanks in advance.
