Abstract

This paper presents a 1 V CMOS pseudo differential amplifier using simple rail-to-rail CMFB circuit. The proposed circuit employs the complementary common mode feedback (CMFB) consisting of common mode detector, transimpedance and transconductance amplifiers. The simulation results using HSPICE under a 0.18 μm CMOS technology shows that the rail to rail output swing is achieved with low common mode gain (-36 dB). The differential output swing of the circuit is ± 0.7 V. The power dissipation of the circuit is 0.23 mW. © 2006 IEEE.
