Abstract
An output stage circuit includes a first P-type metal-oxide-semiconductor transistor, a second P-type metal-oxide-semiconductor transistor, an N-type metal-oxide-semiconductor transistor, and a current source. A voltage of a third terminal of the first P-type metal-oxide-semiconductor transistor is a first voltage minus a voltage drop between a first terminal and a second terminal of the first P-type metal-oxide-semiconductor transistor. The N-type metal-oxide-semiconductor transistor is coupled between the third terminal of the first P-type metal-oxide-semiconductor transistor and the current source. A second terminal of the second P-type metal-oxide-semiconductor transistor is coupled to the third terminal of the first P-type metal-oxide-semiconductor transistor. When a second terminal of the N-type metal-oxide-semiconductor transistor receives a kick signal, a driving current flowing through the second P-type metal-oxide-semiconductor transistor is relevant to the voltage of the third terminal of the first P-type metal-oxide-semiconductor transistor.
