0.7 V Supply SC Circuits with Relaxed Slew Rate Requirements Using GB-Enhanced Multiple-Output Class AB/AB Op-Amps

Year: 2025

Type: article

Abstract: A family of improved low-voltage switched-capacitor circuits is introduced. It is based on the utilization of multiple-output class AB/AB op-amp architectures that provide true sample and hold outputs that are not subject to a reset phase as with conventional switched-capacitor circuits. This feature essentially relaxes the op-amp slew rate requirements, allowing a higher speed and simple low-voltage operation. A power-efficient GB boosting technique based on resistive local common mode feedback is used to significantly improve the GB and internal/external slew rate of the op-amps with only a 36.5% additional power dissipation.
