Abstract
A compensator for maintaining the amplification of one or more electronic signal amplifiers independent of fluctuations in the voltage and/or currents supplied to the amplifiers from voltage and/or current sources. A dummy amplifier is used which is substantially similar to the amplifier whose amplification is to be compensated and which is connected to the same sources. The changes in the output of the dummy amplifier are amplified and used to control a variable load which loads down, or alters, one or more of the voltage or current sources to the extent necessary to maintain the output of the dummy amplifier independent of variations in the voltage and/or current sources. Since the output of the dummy amplifier is maintained constant independent of supply variations, the outputs of the similar, electronic signal amplifiers also are maintained independent of supply variations.
