Abstract: A modular hub driver architecture may include a multi-delay block configured to provide an enhanced delay match among N distinct stages of a distributed modulating electro-optical interface core. The electro-optical multi-core modulator driver may include an input impedance matching stage and a pre-conditioning circuit configured to generate a number M, an integer divisor of N, of delayed replicas of an electrical modulating signal. The electro-optical multi-core modulator may include an array of M launch buffers of the replica signals, and an array of M multi-delay blocks, each including delay circuit modules differently cascaded on distinct signal paths, and configured to receive, at respective inputs, the M replica signals and to output N/M differently delayed replicas of the input signals, each driving a correspondent output stage of one on the N electro-optical interface cores.
