چکیده
WREN d-e signals are to be amplified, the usual approach is to use a direct-coupled circuit. The difficulty of maintaining sufficiently low drift in a direct-coupled configu ration led to the development of chopper and chopper-stabilized circuits, where a mechanical chopper reduces drift to low values. Unfortunately, other shortcomings arise, and in most applications the direct-coupled d-e amplifier ·would be preferable if the drift could be
