ABSTRACT OF THE DISCLOSURE The invention relates to an integrated circuit arrangement for the envelope curve rectification of an amplitude-modulated signal. A differential amplifier is operated by the HF signal. The differential-amplifier negative feedback consists of a const- ant current source. The operative points of the differential amplifier-transistors are maintained constant in that the collec- tors are provided with a negative feedback via rectifiers and a current amplifier to the emitters of the differential amplifier transistors. The emitter potential of the differential amplifier transistors thus exactly follows the peak amplitude of the HF signal. The circuit can be used in integrated circuit form with a small amount of outer wiring. A large linearity range is obtainable.
