  • Publication number: 20220311397
    Abstract: An amplifier circuit includes a differential input terminal, a first power supplier, an amplifier, and a current redistributor. A differential input terminal includes a first differential pair of a p-type and a second differential pair of an n-type, and receives an input voltage. A first power supplier supplies a bias current to the differential input terminal. An amplifier receives an output current of the first differential pair and an output current of the second differential pair, and applies an amplified current to an output node. A current redistributor receives the output current of the first differential pair and the output current of the second differential pair, and provides a redistribution current to the differential input terminal.
