Latest Patents
One of Eric's latest patents is titled "Digitally assisted feedback loop for duty-cycle correction in an injection-locked PLL." This invention discloses a system that performs a duty-cycle correction operation for an injection-locked phase-locked loop (PLL). The system first obtains a pattern of positive and negative error pulses at the rising and falling edges of a reference clock signal. It then multiplies this pattern by a duty-cycle distortion template to calculate duty-cycle distortion values. The system accumulates these values to produce a duty-cycle-error amplitude, which is used to compensate for timing errors caused by duty-cycle variations in the reference clock signal.
Another notable patent is "In-situ ring-resonator-modulator calibration." In this invention, a ring-resonator modulator receives an optical signal and monitors a performance metric of a monitor optical signal. Control logic in the optical device adjusts the resonance wavelength based on the monitored performance metric, ensuring optimal performance of the optical device.
