Abstract
A single-end amplifier includes: a noise cancelling circuit, coupled to a power supply, configured to receive a power signal and to cancel a part of ripples and noises in the power signal to generate an initial signal; an amplifying circuit, configure to receive the initial signal at a first end of the amplifying signal, and to amplify the initial signal to generate a first signal at a second end; and a first transmitting circuit, configured to receive the power signal and to generate a second signal at the second end of the amplifying circuit. The first signal and the second signal are superimposed and outputted to cancel most part of the ripples and noises in the power signal. The noise cancelling circuit includes a first capacitor and a first choke coil.
