Claim 0:
1. An amplifier circuit having a first output terminal and a second output terminal, comprising:
a first charge-steering amplifier comprising a first input terminal, a second input terminal, a first capacitor, and a second capacitor and configured to amplify a first input signal during a first operation period;
a second charge-steering amplifier comprising a third input terminal, a fourth input terminal, the first capacitor, and the second capacitor and configured to amplify a second input signal during a second operation period;
a first switch coupled between the first output terminal and a first target voltage or a second target voltage; and
a second switch coupled between the second output terminal and the first target voltage or the second target voltage;
wherein the first capacitor is coupled between the first output terminal and a reference voltage, the second capacitor is coupled between the second output terminal and the reference voltage, the first capacitor and the second capacitor charge during the first operation period, and the first capacitor and the second capacitor discharge during the second operation period.
