ABSTRACT:
An integrator for use in a switched capacitor-filter, in which switching elements are connected to an input and to an output of an operational amplifier included in the integrator for clamping the input and output to a ground potential during suspension of the integral operation, in order to prevent potentials at the input and output of the operational amplifier from varying and hence ensure rapid stabilization of the integral operation of the integrator.
