Title: Computing the gain
Post by xn47 on Jun 13^th, 2007, 2:35am

Is computing the gain of this circuit, using half circuit analysis is just RL/re?

or I have to consider the effect of the current source.. If I use a resistor or any current mirror as my current source ??

What's the effect on the gain?

This is the simplest diff pair. gmRl. Read Gray and Meyer and repent.
