A novel topology for the offset-compensation and input-matching network of high gain differential amplifiers, tolerant with respect to parasitic effects of bonding wires, is presented. An IC for an optical receiver featuring this network has been designed, and simulations and measurements show high offset suppression (20 dB) and good input matching (Gamma in < -10 dB) over a wide bandwidth (100 kHz - 3 GHz) when considering bonding wires some millimeters long
