In this paper a switched-opamp with a fast common mode feedback (CMFB) circuit is presented. The fully differential two stage amplifier needs CMFB only for the second stage, and thus a fast and simple passive CMFB-circuit may be used. The amplifier is capable of 1 volt operation and has no limitation on the maximum supply voltage
