Abstract
A limiter circuit comprises a first and second differential transistor amplifiers, with the collectors of the transistors of the second amplifier receiving the outputs of the first amplifier. A high gain amplifier has its inverting and non-inverting inputs connected to the output of the first differential amplifier, and has its output connected to the base of one of the transistors of the second amplifier through a feedback network. The differential amplifiers have respective current sources, the current sources of the second amplifier providing a larger current than that of the first amplifier.
