Abstract

PURPOSE: To enable to reset quickly and surely, by connecting two anti-parallel diodes between the input terminals of operational amplifier, and providing the auxiliary circuit and the switch with the circuit consisting of them and the feedback capacitor.
CONSTITUTION: The diodes D1, D2 are connected in anti-parallel to the input of the operational amplifier OP, and the switches SW1, SW2 and the first and second auxiliary power supplies of opposite polarity are provided for the circuit consisting of the diodes and the feedback capacitor Cf. When the capacitor Cf is charged as the polarity shown in Fig., the switch SW1 is closed with the reset instruction RS1, the voltage +E in opposite polarity as the charge voltage of Cf is fed via the diode D2, and the terminal voltage across Cf is instantly zeroed. When Cf is charged with opposite polarity than Fig., the switch SW2 is closed with the reset instruction RS2,the voltage of -E is given to Cf via the diode D1, and the terminal voltage of Cf is instantly zeroed. By arbitrarily setting the value of the voltage E, the initial voltage of Cf at set can arbitrarily be determined.
