ABSTRACT:
A detector circuit for detecting AM and FM signals adapted particularly for integrated circuit fabrication which has a circuit configuration that provides highly stable operating characteristics for both AM and FM operation and is responsive to an increased dynamic range of AM signals. The circuit is uniquely designed to exhibit minimal bias and output voltage variations in the presence of unavoidable IC process changes from one circuit to another and ambient temperature changes, by employing an arrangement of circuit components that readily compensate for such changes.
