Ring modulator baseline wander compensation

A transmitter for use in an optical interconnect, wherein the transmitter comprises:

• a ring modulator;
• an input signal path to provide a data stream to the ring modulator, wherein the data stream has a frequency;
• a monitor photo detector (MPD) coupled with an output of the ring modulator, wherein the MPD is to provide a feedback signal related to the output of the ring modulator;
• and
• biasing circuitry to provide a time-varying direct current (DC) voltage bias to the ring-modulator based on the feedback signal, wherein the biasing circuitry includes an integrator, a voltage gain amplifier (VGA), a voltage combiner, and a biasing network.
