Abstract
A system and method for compensating a parasitic capacitance on a differential amplifier output includes a first differential output and a second differential output of the differential amplifier. The first differential output coupled to the second differential output by a first conductor that has a length of about one half wavelength. The first and the second differential outputs have a parasitic capacitance that can be measured. A second conductor is coupled to the first differential output. The second conductor having a length that is less than or equal to about one quarter wavelength and has an inductive reactance that offsets a capacitive reactance of the parasitic capacitance.
