Date 1997 Abstract Abstract of NL 1001231 (C2) The input voltage is fed to the inputs of an operational amplifier via a chopping reversal switchThe CMOS operational amplifier has a current source and a current mirror. The operational amplifier output is fed to an output circuit. The possible offset voltage is suppressed by the operation of a synchronised chopper circuit between the drains of the CMOS transistors and the current mirror.
