Abstract

PURPOSE:To achieve a phase synchronous circuit which controls the oscillation frequency of a voltage control oscillator based on the output voltage of a voltage holding circuit, and thus to avoid occurrence of the blind sector or gray zone which are caused by the delay of the logic gate group, thus ensuring an accurate phase synchronization.
