Abstract
Systems and methods for driving an optical modulator are provided. In one embodiment, a modulation drive circuit comprises: a balanced impedance network having a first and a second output generated from a first input, and a third and a fourth output generated from a second input, wherein the first and second outputs are balanced with one another, and the third and fourth outputs are balanced with one another; a first differential amplifier, wherein an inverting input of the first differential amplifier couples to the first output of the distribution network and a non-inverting input of the first differential amplifier couples to the third output of the distribution network; and a second differential amplifier, wherein an inverting input of the second differential amplifier couples to the fourth output of the distribution network and a non-inverting input of the second differential amplifier couples to the second output of the distribution network.
