Abstract

PURPOSE:To ralize a compact and inexpensive system by leading a pumping circuit into the input stage of an arithmetic amplifier for a resetting circuit consisting of an arithmetic amplifier containing a CR time constant circuit. CONSTITUTION:A resistance R8, a capacitor C5 and a diode D4 are connected in series through an I/O port P1; and at the same time a resistance R10 and a diode D2 are conncted in series through an I/O port P2. In addition, a diode D3 having the same polarity as a diode D4 is pushed in between an earth and the middle of the C5 and D4. In the same way, a parallel circuit of a capacitor C6 and a resistance R9 is put in between an earth and the middle of the D4 and a comparison input 11. Then a resistance R3 and a capacitor C7 are connected to the area between a power supply and an earth through the middle part between a resistance R10 and the D2.
