Abstract

PURPOSE: To supply only the waveform of a given amplitude to the operation processor, by rejecting the minute amplitude waveform immediately after the application of voltage to the oscillator circuit, through the output picked up from the oscillation circuit including the piezoelectric vibrator via the Schmidt circuit.
CONSTITUTION: The oscillation circuit is constituted with the complementary MOS inverter consisting of N thpe MOSFET1 and P type MOSFET2, feedback resistor 3, crystal oscillator 4, and capacitors 5 and 6. Next, the output of the oscillation circuit thus constituted is fed to the input of the Schmidt circit 12, and the output of the circuit 12 is fed to the operation processor 13. The Schmidt circuit is constituted with the resistors R1 and Ro determining the hysteresis performance and the inverters 16, 17 in series connection, forming the feedback loop via the resistor Ro. Thus, the output of the oscillation period unstable immediately after the power application can be inhibited with the circuit 12 and the operation of the unit 13 is ensured.
