Abstract
A charge-steering amplifier circuit and a control method thereof are provided. The charge-steering amplifier circuit is used for amplifying a differential input signal and includes a sample-and-hold circuit, a charge-steering amplifier, a reference voltage generation circuit, and a switch circuit. The sample-and-hold circuit is configured to sample the differential input signal to generate first and second sampled signals. The charge-steering amplifier has a first input terminal, a second input terminal, a first output terminal, and a second output terminal. The first and second input terminals receive the first and second sampled signals, respectively. The reference voltage generation circuit is configured to generate a reference voltage according to the differential input signal. The switch circuit is configured to couple the reference voltage to the first output terminal and the second output terminal.
