Abstract

This paper presents a low voltage CMOS pseudo differential OTA using simple feed-forward technique. The circuit employs feed-forward technique to suppress the common-mode gain, and positive feedback to enhance the output impedance. The circuit is designed using 0.18 μm CMOS technology under 0.5 V supply. The simulation results show rail-to-rail input/output swing, achieved with low common-mode gain (-35 dB). The output swing of the circuit is 0.3 Vpp. The power dissipation of the circuit is 50 μW. © 2011 IEEE.
