  • Circuit configuration for low-distortion signal switching
    Patent number: 4937478
    Abstract: A circuit configuration for low-distortion switching of signals to a given operating potential includes a countercoupled operational amplifier having an output, a push-pull end stage connected to the output, a differential amplifier stage connected to the push-pull end stage, a switchable resting current source for the differential amplifier stage, and a segment to be switched. The segment has end points being defined by the output of the operational amplifier and a reference potential being the reference potential of the operational amplifier.
