Abstract :
This paper presents a fully differential opamp design based on the switched-opamp approach. The common mode feedback of the proposed opamp only works on the output stage in order to allow a fast turn-on. The opamp was designed in a 0.35 μm CMOS technology and is able to operate from a single 1 V supply
