Abstract : The patent relates to an integrated feedback active filter/integrator which processes electrical signals and performs bandpass and lowpass filtering or integration and double integration. The integrating and double integrating features are obtained by setting the quality factor of the bandpass filter to one half. This provides accurate integration for all frequencies greater than about ten times the center frequency of the filter. The circuit integrates the output and returns (feeds back) this value in the negative sense to the circuit input.
