Abstract
A micropower single-stage folded cascode amplifier able to drive a wide range of capacitive loads is presented. It features class AB operation and includes power-efficient adaptive biasing techniques, which provide enhanced dynamic output current boosting and gain-bandwidth product (GBW). Phase lead compensation is used to improve phase margin and settling performance for low capacitive loads. Measurement results for a 0.5 μm CMOS process show a FoM of 5540 MHz pF/mA, the highest one reported to date for a folded cascode amplifier to the authors' knowledge.
