A CMOS inverter-based class-AB pseudo differential amplifier for HF applications

This paper presents a CMOS inverter-based class-AB pseudo differential amplifier for HF applications using new simple rail-to-rail CMFB circuit. The proposed circuit employs two CMOS inverters and the complementary common-mode feedback (CMFB) consisting of current mode common-mode detector and transimpedance amplifiers. The circuit has been designed using 0.18 µm CMOS technology under 1 V supply, and the simulation results shows that the rail to rail output swing is achieved with low common-mode gain (−15 dB). The output swing of the circuit is 0.7 V. The power dissipation of the circuit is 96 µW.
