Title: A question about the output stage of a OPA
Post by wjx197733 on Mar 29^th, 2006, 2:39am

Hi, all: please look at this circuit which can be found in the book writed by Gray.
I do not know:
1. why this can improve the output swing,
2. why a large bandwith can prevent the crossover distortion?
3. why increase the quiescent current can reduce the crossover distortion?
