1. An integrated electro-optical modulator interface comprising:

  • a two-branch output stage comprising a plurality of CMOS transistors, each branch of said two-branch output stage comprising two stacked CMOS inverter pairs from among said plurality of CMOS transistors;

    said two stacked CMOS inverter pairs of a given branch being configured to drive a respective load, in phase opposition to the other branch; and

    a pre-driver circuit configured to receive a differential modulating signal and output, to respective inputs of said 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.
