Abstract
This document discusses, among other things, an amplifier circuit including first and second amplifiers configured to receive an input signal and to provide a differential output signal using a feedback loop including a transconductance amplifier. A non-inverting input of a first amplifier can be configured to receive an input signal. The feedback loop can be configured to receive the outputs from the first and second amplifiers and to provide a feedback signal to the non-inverting input of the second amplifier, for example, to reduce a DC offset error or to increase a dynamic range of the amplifier circuit.
