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 amplifier with 20dB gain, the pole will always be a decade higher than the zero.

“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.”
