Design of a CMOS fully differential switched-opamp for SC circuits at very low power supply voltages

摘要

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 /spl mu/m CMOS technology and is able to operate from a single 1 V supply.
