ABSTRACT
At present, all but the smallest d-c analogue computers employ some method of drift stabilization to reduce drift at the output of the computing amplifiers. The method most often used is called chopper stabilization. With this method, some drift-free gain is added to the forward loop of a d-c feedback amplifier. If the added drift-free gain is placed in the loop ahead of the primary sources of drift, the steady-state drift with stabilization is equal to the drift without stabilization divided by the amount of drift-free gain added. The required drift-free gain can be achieved with a chopper and an associated stabilization amplifier.
