Abstract: Phase detectors are provided. In one example, The phase detector may include a first transistor leg and a second transistor leg. Each of the first transistor leg and the second transistor leg may include a pair of transistors coupled together at a plurality of common nodes. The phase detector may include an input at the first transistor leg. The input may be configured to receive a first input signal and a second input signal. The phase detect may include an output coupled to the second transistor leg. The output may be configured to provide an output signal. The output signal may include a component indicative of a phase difference between the first input signal and the second input signal.
