Adaptive biasing technique to convert pseudo-class AB amplifier to class AB

An essential modification to a conventional four-stage pseudo class AB amplifier results in a true class AB amplifier. As opposed to the conventional pseudo class AB scheme, which uses a current mirror in the third stage, this work uses an adaptive biasing circuit in the third stage to drastically r...
