Title: Limiting amplifier

Abstract: A limiting amplifier comprises a first differential amplifier having a transistor to which an input signal is applied and a transistor to which a constant voltage is applied. A second differential amplifier amplifies the output of the first differential amplifier. A DC component of the output of the second differential amplifier is applied as a negative feedback to the input side of the first differential amplifier. A limiting circuit is connected between a point which is connected to the output side of the second differential amplifier and a terminal for supplying constant voltage. The resulting differential amplifier is especially well suited for incorporation in a monolithic circuit.
