Systems and methods for amplifying an input signal include amplifier circuitry, an itail connection coupled between a positive voltage circuitry and the negative voltage circuitry and operable to generate an itail voltage corresponding to a greater of the positive voltage input signal (Vp) and the negative voltage input signal (Vn), a first resistor rgp disposed to receive the itail voltage and a first voltage corresponding to Vp, and a second resistor rgn disposed to receive the itail voltage and a second voltage corresponding to Vn. A first current output node is coupled to the output of rgp and operable to output a positive output current (Ioutp) corresponding to the current flowing through rgp, and a second current output is coupled to the output of rgn and operable to output a negative output current (Ioutn) corresponding to the current flowing through rgn.
