Abstract

PURPOSE: To eliminate the integration error dependent upon resistance components of a Zener diode by opening the Zener diode for a small output voltage in an integrating circuit where an operational amplifier is used and the Zener diode is connected as limiter circuit.
CONSTITUTION: Comparator 8 which detects the magnitude of the output of operational amplifier 1 is provided, and the series circuit of Zener diodes 5 and 6 is connected to operational amplifier 1 through switch 9, which is operated by the output of comparator 8, so that a limiter circuit may be constituted. When the output voltage of operational amplifier 1 is small, Zener diodes 5 and 6 are opened, and no integration error dependent upon resistance components of these diodes is generated. When the output voltage of operational amplifier 1 becomes near the destruction voltage of Zener diodes 6 and 5, an output is generated in comparator 8, and switch 9 connects Zener diodes 5 and 6 to protect the whole of the circuit.
