Abstract
A phase detector which includes gated current generators for converting one of two signals which are to be phase compared into a periodic signal of generally triangular form. The other of the two signals triggers periodic sampling of the triangular signal. A 'hold' capacitor stores the sampled signals between sampling intervals, and provides the phase detector output signal. Logic gating disables the current generators during the sampling intervals so that the amplitude of the triangular waveform will not change during those intervals.
