ABSTRACT:
A limiter amplifier with a power supply has a plurality of cascade-connected differential amplifiers for limiting the amplitude of an input signal. Each of the amplifiers has a first constant current circuit. A biassing circuit, having a second constant current circuit, is connected to the input of the differential amplifier for supplying its biassing needs. A third constant current circuit activates the first and second constant current circuits. A voltage regulator is connected to the power supply for providing a constant voltage to each of the three constant current circuits. The voltage regulator and the first to third constant current circuits have the same temperature characteristics.
