Abstract: A high-rate high-swing drive circuit applied to a silicon photonic modulator is disclosed. The drive circuit is connected to a drive pre-stage circuit and a modulator load. The drive circuit includes at least one output circuit, and the output circuit includes: a first inverter, a first voltage bias module, a second inverter, a second voltage bias module, and an inductor. The drive circuit formed by using such a circuit connection increases an output swing of a drive while ensuring a high rate.
