Abstract
A phase selector/phase interpolator circuit which includes two phase selector circuits and one phase interpolator circuit, each phase selector circuit includes N first tail current tubes, N phase selector units, a current source circuit and a comparison circuit. The current source circuit is selected as a load of the phase selector circuit. The comparison circuit compares a common-mode voltage of the two output clock signals output from the phase selector unit with a reference voltage, and performs negative feedback regulation on the first bias voltage of the first tail current tubes, so that the common-mode voltage can be controlled to be equal to the reference voltage, a tail current of the first tail current tubes is controlled to be equal to the current of the current source circuit, and the output waveform becomes a linear triangular wave.
