  • Abstract
    Radio frequency interference superimposed on the input nominal signals of an operational amplifier excites distortion phenomena in active nonlinear devices. In actual differential input stages, interference generates even-order harmonics and in particular DC offset voltage. A new frequency selective input differential stage is presented, which minimises the generation of DC offset voltage due to distortion phenomena
