Peak-to-peak signal detection apparatus adapted for construction in monolithic integrated circuit form. The base-emitter junctions of three like conductivity transistors are direct current coupled in cascade across a source of forward bias voltage (e.g., 3VBE). Signals to be detected are capacitively coupled to the junction of the base of the second and the emitter of the first transistors. A detector filter capacitor is connected across the base-emitter of the third transistor. Peak-to-peak detected signals are provided at the output of the third transistor.
