Abstract

PURPOSE:To correct the time error due to the delay in the leading of power supply for the circuit at power supply application, by taking the frequency of reference time pulse inputted to the count circuit as n times the reference value before the voltage stabilization and taking it as the reference value after stabilization. CONSTITUTION:The constant voltage power supply 1 setting the voltage at steady state several times higher than the minimum operation voltage of the circuit, is provided, and the reset circuit 2 setting the count circuit 4 detecting the voltage set to lower value than the stable voltage and more than the minimum operating voltage of the circuit at the leading of the power supply voltage is provided. Further, when the voltage is more than the minimum operation voltage, the count citcuit 4 starts operation and the frequency of the reference time pulse inputted to the count circuit 4 is made n times the reference value inputted to the count circuit 4 before voltage stabilization, with the output of the power supply stabilization detection circuit 5 detecting the power supply reaching the stable voltage, and it takes the frequency as the reference value after stabilization. Thus, the frequency between the start of count to the power supply stabilization is made higher, and the time up to the count start is corrected, allowing to reduce the time error due to the delay in the leading.
