Confusion with a simple two stage amplifier design example
The PNP is a follower, as you mentioned, so Ve2 approximately follows Ve1 with an offset of about a diode drop, as the previous comment mentioned. The collector emitter current of a transistor is an exponential function of the base emitter voltage. That is to say that a small change in emitter voltage will cause a large change in emitter current. If you decrease Ve1, the emitter current in the follower with increase, resulting in a fall in emitter voltage. This then results in a decrease in emitter current until everything balances again. So you have negative feedback. This is how it follows, with a gain slightly less than 1.
