Abstract :
A method for drift reduction in d.c. amplifiers is described. This reduction is obtained using the principle of ´adding the lacking part´. The d.c. stabilisation device is a chopper amplifier. The circuit is such that the chopper amplifier does not affect the frequency response of the wideband amplifier.
