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 gainbandwidth
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 readjust A in order t...
