Patent ID: 8902003

Claim:
An amplifier, comprising: an amplifying stage configured to provide an amplifier output signal based on a received amplifying stage input signal and a received amplified version of the amplifying stage input signal; a gain stage configured to receive the amplifying stage input signal and provide the amplified version of the amplifying stage input signal based on the received amplifying stage input signal; wherein the gain stage comprises an amplifying element and a biasing element; wherein the amplifying element of the gain stage is configured to receive the amplifying stage input signal or at least a differential component of the amplifying stage input signal and provide based on the received amplifying stage input signal or the differential component of the amplifying stage input signal and a gain stage bias provided by the biasing element the amplified version of the amplifying stage input signal or at least a differential component of the amplified version of the amplifying stage input signal; wherein the amplifying element of the gain stage comprises a transistor; wherein a control terminal of the transistor of the gain stage is configured to receive the amplifying stage input signal or at least the differential component of the amplifying stage input signal; wherein the transistor of the gain stage is configured to provide the amplified version of the amplifying stage input signal or at least a differential component of the amplified version of the amplifying stage input signal at a first terminal of the transistor of the gain stage; wherein the biasing element of the gain stage is configured to provide the gain stage bias at the first terminal of the transistor of the gain stage; wherein the gain stage comprises a further biasing element configured to provide a further gain stage bias at a second terminal of the transistor of the gain stage.
