Abstract
An improved half-wave rectifying circuit is described employing a high-gain differential amplifier including a negative feedback means for stabilizing the amplifier gain and including means for supplying an offset current and an operating bias at the amplifier input with the feedback, offset and biasing means including a number of resistors which are proportioned to provide a substantially zero output in the absence of an input signal and to provide an output which is a half-wave rectified output replica of an oscillating input.
