Claim 0:
1. An amplifier with a power stage comprising:
a first Zeta converter connectable to a power supply and a load;
a second Zeta converter connectable to the power supply and the load, the second Zeta converter being driven by a complementary duty cycle relative to the first Zeta converter; and
a controller configured to provide an audio signal to the first Zeta converter and the second Zeta converter for delivery to the load, wherein the controller is connected to the load to receive a voltage feedback signal, and wherein the voltage feedback signal comprises a differential-mode correction signal comprising a difference between a voltage output of the first Zeta converter and a voltage output of the second Zeta converter.
