Abstract
An amplifier circuit applied to a source driver of a display apparatus includes a first input terminal, a second input terminal, an operational amplifier, an output stage and an output terminal. The first input terminal receives a first input signal. The second input terminal receives a second input signal. The operational amplifier is coupled to the first input terminal and second input terminal and receives the first input signal and second input signal and outputs a first control signal and a second control signal respectively. The output stage includes a first BJT and a second BJT coupled in series between a first terminal and a second terminal. The first BJT and second BJT are coupled to the operational amplifier and receive the first control signal and second control signal respectively. The output terminal is coupled between the first BJT and second BJT and outputs an output signal.
