ABSTRACT:
A tracking sample and hold phase detector operating as an error sampled feedback loop which takes signal samples during successive periods of an input signal with a sampling gate, holds the signal sample in a storage gate, and feeds back the sample to the sampling gate to allow the bias of the sampling gate to track the input signal level, thereby maintaining balance of the tracking circuit. A fast comparator detects the zero crossing level of the downconverted signal which is comprised of successive signal sample steps and has the shape of the input signal. The sampling gate comprises a diode bridge enabled by a balanced strobe, the input signal and the strobe being close or equal in frequency, the frequency of the downconverted signal being the difference frequency.
