Abstract:

An apparatus for generating an output current including a first distortion current based on a first transconductance and a second distortion current based on a second transconductance is disclosed. The first distortion current may be generated by an amplifier and the second distortion current may be generated by a distortion compensator. The second transconductance may be less than the first transconductance. In some implementations, the second distortion current may reduce the first distortion current output by the apparatus.
