  • Abstract
    Novel class AB OTA topologies result from the combined use of local common-mode feedback and class AB input stages. They can operate at low supply voltage and feature very low static power consumption, bandwidth enhancement, and very high slew rate. Measurement results of a 0.5 μm CMOS prototype show slew rate and unity-gain bandwidth enhancement factors of 180 and 4.5, respectively, compared to a conventional one-stage OTA.
