Abstract
A modulator driver for Mach Zehnder optical modulators is described. The modulator driver may be configured to limit power consumption while preserving linearity of the response. A modulator driver may comprise a first transconductance stage, a second transconductance stage and a current buffer. The current buffer may be configured to drive the radio-frequency path (RF) of a Mach Zehnder modulator with output signals. The first and second transconductance stages may be configured to decouple the path corresponding to the alternating current (AC) from the path corresponding to the direct current (DC). The first and second transconductance stages may additively combine the respective AC signals while subtractively combine the respective DC signals.
