Abstract
Radio frequency interference superimposed on the input nominal signals of a n operational amplifier excites distortion phenomena in active nonlinear de vices, In actual differential input stages, interference generates even-ord er harmonics and in particular DC offset voltage, A new frequency selective input differential stage is presented, which minimises the generation of D C offset voltage due to distortion phenomena.
