Abstract

See full text

The application discloses a circuit, including: a positive-terminal p-type transistor; a negative-terminal p-type transistor; a positive-terminal n-type transistor, wherein the positive-terminal p-type transistor and the positive-terminal n-type transistor are cascoded between a first reference voltage and a second reference voltage; a negative-terminal n-type transistor, wherein the negative-terminal p-type transistor and the negative-terminal n-type transistor are cascoded between the first reference voltage and the second reference voltage; a first positive-terminal capacitor, a top plate of the first positive-terminal capacitor is coupled to a gate of the positive-terminal n-type transistor; a first negative-terminal capacitor, a top plate of the first negative-terminal capacitor is coupled to a gate of the negative-terminal n-type transistor; a first control circuit, arranged to generate a first control signal to bottom plates of the first positive-terminal capacitor and the first negative-terminal capacitor according to the positive-terminal output signal, the negative-terminal output signal and the target common mode voltage.
