  • Abstract
    A simple two-stage Miller compensated class AB amplifier is presented which uses single-ended class AB control for accurate setting of the output stage quiescent and minimum currents. This control technique also inherently boosts the amplifier midband positive power supply rejection ratio (PSRRdd). Measurements show a more than 20 dB improvement in the midband PSRRdd when the amplifier is compared to popular symmetrical class AB amplifiers with similar bandwidth.
