Abstract
Circuits and methods to achieve a new fully differential amplifier topology in class AB mode are disclosed. In a preferred embodiment of the disclosure the differential amplifier is diving dynamic speakers. An differential intermediate stage combines four different feedbacks, all sharing four high impedance nodes: main loop regulation feedback, common mode regulation feedback, and output stage quiescent current regulation for both differential output stage branches.
