Abstract:
A feedback circuit coupled between an input terminal and an output terminal of an amplifier circuit includes an input terminal, an output terminal, a first set of transistors and a second set of transistors. The first set of transistors is coupled between the input terminal and the output terminal of the feedback circuit, and includes a first terminal, a second terminal, and a control terminal used to receive a first control signal to turn on or off the first set of transistors. The second set of transistors is coupled between the input terminal and the output terminal of the feedback circuit, and includes a first terminal, a second terminal, and a control terminal used to receive a second control signal to turn on or off the second set of transistors.
