Abstract
The present invention provides a differential to single-ended converter including a first input node, a second input node, an operational amplifier and a feedback circuit. The operational amplifier has a first terminal and a second terminal, wherein the first terminal of the operational amplifier receives a first signal from the first input terminal, and the second terminal of the operational amplifier receives a second signal from the second input terminal. The feedback circuit is configured to receive an output signal of the operational amplifier and generate a first feedback signal to the first terminal of the operational amplifier to reduce a swing of the first signal, and generate a second feedback signal to the second terminal of the operational amplifier to balance noises induced by the feedback circuit and inputted to the first terminal and the second terminal.
