Abstract :
A fully differential, low-voltage, low-power, fast settling operational amplifier is presented. The proposed circuit employs a novel continues-time common-mode feedback and a slew rate enhancement circuit. With a bulk control circuit, the proposed amplifier would find applications in very low-power switched-capacitor circuit.
