Unformatted text preview: th goes to zero as AG → 1. G Note that the gain of the regenerative amplifier at the center frequency is |T (ωo )| = 1−AG , so the gain goes to infinity as AG → 1. The product of the peak gain and the -3 dB bandwidth is called the gain-bandwidth product (GBP), and is ωo G. Notice that GBP does not depend on the amount of feedback, A. This is useful Q to know — suppose that you know the gain and bandwidth for one value of A. Then you immediately know that if you re-adjust A in order t...
