ABSTRACT:
A detector is disclosed for receiving an AC signal and for generating a DC output signal indicative of the level of the input signal. The detector includes an amplifier receiving the input signal and a first transistor stage which responds to the amplifier output by developing increasing or decreasing levels of current, depending on the polarity of the amplifier's output. Second and third transistors sense those increasing and decreasing current levels for developing two intermediate currents of the same polarity. The intermediate current are coupled to a load across which a fully rectified output signal is developed.
