Abstract
Methods and systems for a photonically enabled complementary metal-oxide semiconductor (CMOS) chip are disclosed and may comprise in an integrated circuit comprising a driver: amplifying a received signal in a plurality of partial voltage domains, and generating the partial voltage domains in a domain splitter in the driver. A voltage domain boundary value between two partial voltage domains may be controlled utilizing a differential amplifier that samples an output voltage of a cascade amplifier that is an input to the driver and controls a current supplying said cascade amplifier. A series of diodes may be driven in differential mode via the amplified signals. An optical signal may be modulated via the diodes, which may be integrated in a Mach-Zehnder modulator or a ring modulator. The diodes may be connected in a distributed configuration. The amplified signals may be communicated to the diodes via transmission lines, which may be even-mode coupled.
