Abstract

See full text

A phase interpolator includes differential pairs, a switching circuit, an output stage, and a correction circuit. The differential pairs generate a first signal and a second signal according to a first group of input signals and a second group of input signals. The switching circuit is turned on or turned off, according to control signals, to transmit the first signal and the second signal to a current source circuit, in order to control a value of the first signal and a value of the second signal. The output stage generates a first output signal according to the first signal and the second signal. The correction circuit provides and stables a common mode voltage of the first output signal according to the first output signal.
