Abstract
PURPOSE: To realize the setting of an accurate delay time in a digital way by installing the counter which is capable of the digital setting of the division ratio and with no use of the element receiving the temperature effect to the time setting circuit.
CONSTITUTION: Pulse input 6 is supplied to OR circuit 20, inverter circuit 15 and FF circuit 16. Circuit 16 has inversion, and FF circuit 11 turns to "1" to be supplied to circuit 20. Output 8 of circuit 15 opens the gate of AND circuit 21, and clock 9 of fundamental clock generation circuit 19 is supplied to 1/N counter 17. After counting of the clock number, counter 17 delivers FF signal 14 to return to the original state. Circuit 16 is reset by signal 14, and the output of circuit 16 becomes "0". Then the delay completes via circuit 20. In this way, a high stability can be kept for the fundamental clock, accordingly the stability of the delay time being increased.
