Abstract
A signal amplitude limiting circuit includes a differential circuit, a feed back circuit and a voltage supply circuit. The differential circuit has a positive input terminal, a negative input terminal, a positive output terminal and a negative output terminal. The feedback circuit is connected to the differential circuit. The feedback circuit compares voltages at the positive and negative output terminals with a reference voltage and outputs a comparison signal in response to the comparison. The voltage supply circuit is connected to the differential circuit and the feedback circuit. The voltage supply circuit provides a current to the differential circuit in response to the comparison signal.
