Abstract
One aspect of the invention is an integrated circuit ( or ) comprising an amplifier ( or ) having at least two poles in its frequency response and an output impedance compensation circuit (M A, M M AC or M A, M M M AC ) coupled to an output node ( ) of the amplifier ( or ). The output impedance compensation circuit (M A, M M AC or M A, M M M AC ) is operable to create a feedback signal proportional to the impedance of an output load ( ) coupled to the output node ( ), and create a zero in the frequency response of the amplifier ( or ) in response to the feedback signal between the at least two poles.
