Abstract

A drive circuit, a display drive chip, a display apparatus, and an electronic apparatus are provided. The drive circuit includes a first stage circuit, a second stage circuit and an auxiliary circuit. The first stage circuit is configured to receive and amplify a first input signal and a second input signal to acquire a first output signal and a second output signal and output the first output signal and the second output signal to the second stage circuit. The second stage circuit is configured to output a third output signal based on the first output signal and the second output signal to drive a load. The second stage circuit is further connected to the first stage circuit via a Miller capacitor. The auxiliary circuit is connected to the first stage circuit and the second stage circuit for reducing an output impedance of the first stage circuit.
