ω p ω z = R 1 C ( R 1 | | R 2) C = R 1 R 1 | | R 2 = R 1 + R 2 R 2 = 1 + R 1 R 2. That is, the zero and the pole are separated by a factor equal to the amplifier's ideal closed loop gain at DC as set by the feedback network. For an …

Feedback is when a part of the output signal of an amplifier is fed back to the input. NEGATIVE FEEDBACK is when some of the output signal is fed back to the input in such a way as to PARTIALLY cancel the input signal.

“Feedback is an arrangement where an amplifier is made to respond to its own output signal in addition to the wanted input signal and any unwanted disturbances. When the response to an unwanted disturbance is smaller with feedback applied than without it, we call it negative feedback.”

This post is a part of the series on audio amplifier feedback. The contents of the series can be found here.. Since my previous post was about shaping the open loop gain of a long-tail pair (LTP) with an RC network across the load, it seems to be a convenient moment to talk about LR compensation of an LTP:
