Hi there,
Just started to pick up on knowledge on IC design and having problem understand the books. Hope someone can explain to a noob like me.
Q1) In Razavi book, pg 144, figure 5.13, it show a modification of a cascode mirror which is modified from a Cascode Mirror topology. could some one explain to me how it is being done? I have tried and come up with the following method. Is it correct?
