Japanese Patent JPS6244597
Kind Code:
Y2
Abstract:
The switched capacitor comprises a capacitor CA1 and a switching element S1 which can be periodically changed over for charging CA1 with an input voltage YIN and for discharging the capacitor CA1 to one input end (A) of an operational amplifier OP1. Another input end of 0P1 is connected to a reference potential (ground) and an integrating capacitor CB1 is connected between an output end of OP1 and the input end (A) …Switching elements S2 and S3 are connected to input end (A) and the output end of OP1. The switching elements can be closed to make the potentials of the input end (A) and the output end of OP1 equal to the reference potential (ground). …This prevents potentials at input end (A) and the output end becoming unfixed when the integrator is out of operation, and ensures rapid stabilization of operation when the integrator is brought into operation.
