ABSTRACT:
A positive temperature coefficient resistance element such as a sensistor and a negative coefficient resistance element such as a thermistor are arranged in a potential divider network, the output terminal of which produces a potential which is a function of temperature. The potential is applied as a bias potential to the control electrode of an amplifier circuit subject to variations in gain as a function of both control electrode voltage and temperature to reduce the gain, as a function of temperature, of the amplifier.
