Abstract

A receiver for wired communication, includes a DC (direct current) level shift circuit and an analog-to-digital converter circuit. The DC level shift circuit is configured to receive a first signal and generate a second signal, in which the DC level shift circuit comprises a capacitor, and the DC level shift circuit is further configured to transmit a first common-mode voltage in a first voltage domain to a first terminal of the capacitor and transmit a second common-mode voltage in a second voltage domain to a second terminal of the capacitor before the first signal is received, and when the DC level shift circuit receives the first signal, the DC level shift circuit stops transmitting the first common-mode voltage and the second common-mode voltage to the capacitor. The analog-to-digital converter circuit is configured to generate a digital signal according to the second signal.
