Abstract

See full text

Phase detector circuitry includes first mixer circuitry configured to receive a first clock signal and a second clock signal. The first mixer circuitry includes a first plurality of transistors. The first plurality of transistors includes first transistors, second transistors, and an output transistor. The first transistors receive the first clock signal, and the second transistors receive the second clock signal. The first output transistor outputs a first output signal. The first output signal corresponds to a first phase difference between the first clock signal and the second clock signal.
