METHOD FOR REDUCING ERRORS OF DIRECT CURRENT AMPLIFIER WITH MODULATOR AT INPUT AND DEMODULATOR AT OUTPUT Russian patent published in 2013 - IPC H03F3/38

Abstract RU 2498501 C2

FIELD: measurement equipment.

SUBSTANCE: method for reducing errors of a direct current amplifier with a modulator at the input and a demodulator at the output consists in the fact that temperature of the amplifier is measured and a correction signal is shaped, which is added to an output signal of the amplifier; with that, voltage of the correction signal is formed pro rate to the speed of the change of amplifier temperature.

EFFECT: compensation of amplifier temperature error.
