I use GeSi BiCmos 0.35 process to design some circuit. I feel confused about the connection between the component subtrate and the ground. Someone tell me that I shoud conncet the subtrate of the npn or mos transitor to the ground. but someone tell me they did not do so. I want to know the connection between the ground and the subtrate is necessary or optional. And how to know what kind of subtrate of under a type of transistor.
Thanks!
