Abstract
Disclosed herein is an operational amplifier including a non-inverting input terminal, an inverting input terminal, a P-type metal oxide semiconductor input differential pair, a first input tail current source, an N-type metal oxide semiconductor input differential pair, a second input tail current source, an output stage, a first correction circuit, and a second correction circuit. The first correction circuit and the second correction circuit operate over an operation region of the P-type metal oxide semiconductor input differential pair, an operation region of the N-type metal oxide semiconductor input differential pair, and a transition region in which both the P-type metal oxide semiconductor input differential pair and the N-type metal oxide semiconductor input differential pair operate.
