Abstract:
The even order harmonic distortion in a differential circuit is reduced or eliminated by treating the amplitude and phase mismatch sources that cause the distortion as impedance mismatches, and utilizing switched resistor circuitry that adjusts the load resistance to reduce the effects of the amplitude mismatch sources, and switched capacitor circuitry that adds shunt capacitance to reduce the effects of the phase mismatch sources.
