Abstract: A driver circuit for a Mach-Zehnder modulator is provided that includes a first driver having an input to receive one of an input data or input data complement, and an output to be coupled to a first application voltage node associated with a first arm of a Mach-Zehnder modulator. The driver circuit includes a second driver having an input to receive the other of the input data complement or input data, and an output to be coupled to a second application voltage node associated with the first arm of the Mach-Zehnder modulator. The first driver and the second driver differentially drive the first and second application voltage nodes associated with the first arm of the Mach-Zehnder modulator to result in a voltage swing associated with a voltage applied to the first arm that is twice the supply voltage.
