ABSTRACT
Phase detector is the first block of Phase Locked Loop. It is a nonlinear device the output of which contains the phase difference between the two oscillating signals. The advantage in most of the phase detector is that their low frequency response is actually linear over some range rather than sinusoidal. A different view is required in the analysis of digital phase detector from that of classical mixing detectors. The exact behavior of these digital phase detectors should be nonlinear but the low frequency behavior is often linear. The circuit of phase detectors is more important in dealing with specific circuit conditions than to make analysis simpler. The Hogge Phase Detector using Transmission Gate Logic in 45nm CMOS technology is implemented here in LTSpice IV tool because of its small output jitter and selfcorrecting ability and linearity.
