Abstract
Methods and systems for split voltage domain transmitter circuits may include a two-branch output stage including a plurality of CMOS transistors, with each branch of the two-branch output stage comprising two stacked CMOS inverter pairs. The two stacked CMOS inverter pairs of a given branch are configured to drive a respective load, in phase opposition to the other branch. A pre-driver circuit is configured to receive a differential modulating signal and output, to respective inputs of the two stacked CMOS inverters, two synchronous differential voltage drive signals having a swing of half the supply voltage and being DC-shifted by half of the supply voltage with respect to each other. The load may include a series of diodes that are driven in differential mode via the drive signals. An optical signal may be modulated via the diodes.
