Abstract

See full text

A synchronization circuit for a free-running oscillator, in which a multi-tapped delay line provides delayed outputs incrementally spaced throughout the period and at the same frequency as the oscillator. That delayed signal closest in time to a reference signal is selected as the output signal, synchronized to the reference signal.
