PURPOSE:To provide an integrating circuit which can correctly set an output voltage and an integrating time before integration and after integration and perform linearly the time change of an integrating output. CONSTITUTION:To the output edge of an operational amplifier 3, one edge to connect two constant current diodes 5 and 6 in parallel with a cathode and an anode mutually is connected, other edge is connected to the minus input edge of a capacitor 4 for storing and discharging a charge and the operational amplifier 3, guided to an output terminal, the plus input edge of the operational amplifier 3 is guided to an input terminal, and constant voltage powers 1 and 2 are respectively connected to the positive and negative power terminals of the operational amplifier 3. |
