Abstract
A switched op amp with a fast common mode feedback (CMFB) circuit is presented. The proposed 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 V operation and has no limitation on the maximum supply voltage
