ABSTRACT:
An Ahuja compensation circuit includes a feedback loop with a high swing cascode biasing circuit. The high swing cascode biasing circuit includes a frequency boosting circuit. The frequency response of the high swing cascode biasing circuit and the Ahuja compensation circuit are improved by the frequency boosting circuit.
