A CMOS operational amplifier with chopper stabilization and a switched output

The input stage of a CMOS operational amplifier for use in a switched capacitor circuit is chopper stabilized by switches N13-N16 and N9-N12 so as to reduce the effect of flicker noise. Flicker noise (I/f noise) is normally reduced by using large area transistors which consume valuable IC area and w...
