Phase locked signal generator |
摘要 |
A phase locked signal generator comprises an asynchronous oscillator for producing a square wave signal, delay circuits supplied with the output square wave signal of the asynchronous oscillator, which delay circuits are provided in a plurality of stages and the output square wave signal of the asynchronous oscillator is supplied to a delay circuit provided in an initial stage, a latch circuit supplied with the output square wave signal of the asynchronous oscillator and outputs of the delay circuits, which latch circuit simultaneously latches the outputs of the delay circuits responsive to a reference signal applied to the latch circuit, and a gate circuit for producing an input or an output of one or a plurality of delay circuits each having an input and an output of mutually opposite polarities at a time when the reference signal is applied to the latch circuit, as an output square wave signal of the phase locked signal generator.
