Abstract: Methods, systems, and circuits for providing low-noise amplification with input common mode voltage following are disclosed. A circuit includes: an amplifier configured to receive a voltage input having an input common mode voltage and configured to generate a differential voltage output having an output common mode voltage; a feedback circuit in communication with the amplifier, the feedback circuit configured to receive the input common mode voltage and the differential voltage output and to generate a feedback voltage in response to the input common mode voltage and the differential voltage output; and an adjustable current source of the amplifier configured to receive the feedback voltage and to adjust a tail current of the amplifier in response to the feedback voltage.
