摘要：
A switching power amplifier includes: a first transistor controlled by a first digital signal to selectively output a first output signal; a second transistor controlled by a second digital signal to selectively output a second output signal; and a control circuit arranged to generate the second digital signal according to the first digital signal and a third digital signal; wherein the first output signal and the second output signal are outputted on a common connected node of the first transistor and the second transistor.
