Latest Patents

His latest patents include the "Differential receiver circuit with electronic dispersion compensation for optical communications systems." This invention describes a series of differential, balanced high-speed circuits that enable the design of a receiver with Electronic Dispersion Compensation (EDC) on a single semiconductor substrate. It incorporates functions such as an analog Fast Forward Equalizer (FFE), Clock and Data Recovery, and a Decision Feedback Equalizer (DFE). The design is enhanced by additional circuits that allow for control of the slicing level to compensate for pulse distortion and control of the phase offset to optimize eye sampling time when a distorted signal is received. To achieve maximum operational speed, all circuits, including the phase-locked loop, function as differential circuits, featuring numerous improvements in the design of the charge pump, decision feedback equalizer, slicing level control, and more.
