SUMMARYA novel CMOS current-feedback operational amplifier (CFOA) aimed to low-power applications is proposed. The use of a compact class AB implementation allows high current-drive capability and simultaneously very low quiescent power consumption. Measurement results of a fabricated prototype show for an inverting configuration a closed-loop bandwidth of 1 MHz independent of gain setting, and a slew rate of 2 V/ s for a load capacitance of 30 pF and a quiescent power consumption of 264 W.
