Abstract:
The present disclosure provide for active boost in an electrical driver via a frequency comparator, configured to determine operational characteristics of an electrical circuit connected to an optical modulator based on a frequency difference between a ring oscillator and the clock signal; an electrical driver configured to drive a phase shift of a first optical signal carried on a first arm relative to a second optical signal carried on a second arm of an optical modulator, the electrical driver comprising: a first signal pathway, connected to the first arm of the optical modulator, wherein the first signal pathway includes: an adjustable gain inverter, electrically connected to first and second nodes; a fixed gain inverter, electrically connected to the first and second nodes; an inductor electrically connected between the second node and a third node; and a non-inverting amplifier connected between the third node and the first node.
