ABSTRACT:
An output load circuit having a non-linear transfer characteristic is coupled to the differential output of a conventional quadrature detector which produces a more linear version of the S-curve characteristics of the detector. The load circuit comprises differentially connected transistors each having their collector-emitter paths coupled to respective outputs of the multiplied portion of the quadrature demodulator wherein the non-linear differential output signal therefrom drives the non-linear transfer function of the base-emitter junction of the differentially coupled transistors to produce a linear output voltage at the base thereof.
