VARIABLE DELAY CIRCUIT

摘要

PROBLEM TO BE SOLVED: To provide a variable delay circuit that can control a high frequency signal over a wide range with high accuracy by eliminating occurrence of inversion of a delay time increment due to delay dispersion in the circuit. SOLUTION: Gates 101, 102, 103, 104 are used to distribute an input signal into branches, and the number of circuits connected to each branch signal distribution circuit is limited to prevent attenuation in signal waveform so as to realize delay control of a high frequency signal.
