A circuit for removing non-linearity produced when an amplifier includes a load that results in non-linear current levels is provided. The circuit includes a first transistor element being coupled to one of the differential inputs associated with the amplifier. A second transistor element is coupled to another of the differential inputs associated with the amplifier. The second transistor element is coupled to the current associated with the load. Current passing the collectors of the first and second transistors elements are arranged to be always equal so as to eliminate in the circuit the changes between the base currents of the second transistor element and first transistor element caused by the current associated with the load.
