A 0.8 V class-AB linear OTA using DTMOS for high-frequency applications
This paper presents a 0.8 V class-AB linear operational transconductance amplifier (OTA) using DTMOS for high-frequency applications. The circuit employs positive feedback to enhance the input impedance, and feed-forward technique to suppress the common-mode gain. The circuit is designed using 0.18 μm CMOS technology under 0.8 V supply. The simulation results show rail-to-rail input/output swing, suppressed common-mode response, and good linearity (less than −48 dB with input 0.6 Vpp, 5 MHz). The power dissipation is 155 μW.
