Abstract
A switchable operational amplifier is presented for switched op amp technology, in which the current through the pre-stage is reduced during the off phase of the switching clock pulse. In this way, power consumption can be reduced. During the off phase of the switching clock pulse, the current can either be reduced or switched off completely.
