Abstract
PURPOSE: To obtain an enxpensive circuit of simple constitution using inverter circuits and delay circuits, and also to make it possible to set the circuit to an error of an oscillation period much smaller than a dispersion in gate delay time only by operating a switch.
CONSTITUTION: The oscillation circuit is equipped with inverter circuits (NAND circuit) 21 to 24, and delay circuits 25 to 28. In addition, this circuit includes switches 34 to 37, latch circuits 30 to 33, delay circuit 20, and waveform-shaping circuit 29. When there is dispersion in the gate delay time of integrated circuits constituting circuits 21 to 24, circuit 22 is used with switch 35 ON and when the oscillation period is 4% shorter than a desirable value (b), circuit 24 is used with switch 37 ON, so that the desirable value can be obtained. In this case, the dispersion within the range from -5% to +3% against the desirable value can be made into an error within +1% through operations of switches 34 to 37.
