CMOS low-voltage class-AB operational transconductance amplifier

• The authors present a new low-voltage class-AB opt rational transconductance amplifier (OTA). The proposed OTA achieves a fast non slew-rate limited settling time with low power consumption. The circuit is power efficient when driving large capacitive loads. The OTA circuit is well suited For low-voltage low-power switched capacitor applications. Experimental results of the proposed circuit are included.
