Negative FeedbackThe use of negative feedback reduces the gain, but most other rationales favor its use. Part of the output signal is taken back to the input with a negative sign. For an amplifer with negative feedback the gain becomes The large open loop gain of an op-amp makes it possible to build amplifiers whose gain is determined by the feedback B and not by the gain of the amplifying element itself!
