Abstract:
An amplifier device includes an initial amplifier stage configured to receive a differential input signal at a first leg and a second leg; a final amplifier stage coupled to outputs of the initial amplifier stage, the final amplifier stage including a primary signal amplifier and an error amplifier in each of the first and second legs; and wherein an output of the error amplifier of the first leg is combined with an output of the primary signal amplifier in the second leg, and an output of the error amplifier of the second leg is combined with an output of the primary signal amplifier in the first leg.
