Latest Patents

One of his latest patents is titled "Reduction of data skew in parallel processing circuits." This invention involves signal processing circuitry that features parallel processing channels equipped with clock-generation circuitry. This circuitry generates high-speed clock signals to drive the channels and synchronization signals to reset the processing of the channels. The design includes multiple multiplexing channels arranged in macrocells, each containing a phase-locked loop (PLL) that produces a high-speed PLL clock signal and synchronization signals for the channels. Each channel is equipped with a counter that implements a state machine, which is reset to a specified state upon receiving each synchronization pulse.

Another notable patent is "Crosstalk reduction in a backplane employing low-skew clock distribution." This system addresses the issue of crosstalk in backplanes by adjusting the positive-to-negative (P-N) driver skew of a transmit signal from a high-speed differential driver. It also incorporates a high-speed differential subtraction circuit that combines a gain-adjusted replica of at least one transmit signal with a received signal to minimize near-end crosstalk. Additionally, a PLL synchronization circuit is utilized to align timing events between near-end and far-end high-speed interfaces.
