ABSTRACT:
A switching circuit of the type including a plurality of differential amplifiers on an IC chip and having a linear operating range about a bias point, having an operational amplifier connected as a comparator and coupled to an input thereof to receive a modulating signal, one input of the comparator being connected to the bias point so that the output thereof applied to the switching circuit varies about the bias point within the linear range of the switching circuit, and means coupling the signal to be modulated to a second input of the switching circuit so that the signal is bi-phase modulated by the modulating signal with substantial carrier suppression and significantly reduced harmonics.
