Latest Patents

Feng Cheng Lin's latest patents include a "Crossbar integrated circuit with parallel channels for a communication device." This invention features communication circuitry that comprises processing circuitry, parallel channels, and crossbar integrated circuits. The processing circuitry facilitates the exchange of communications between communication links and the parallel channels. The parallel channels enable the transfer of communications in parallel with a clock signal. The crossbar integrated circuits receive the communications and the clock signal over the parallel channels, switch the communications based on the clock signal, and transfer the switched communications back to the parallel channels.

Another significant patent is the "Low-level circuit implementation of signal flow graphs for real-time signal processing of high-speed digital signals." This invention applies signal processing techniques to data rates at state-of-the-art circuit speeds, currently reaching 1.6 Gbit/sec. It utilizes a canonical FIR filter algorithm through hybrid analog and digital circuit techniques. A plurality of digital to analog converters (DACs) generates analog currents that represent the tap coefficients of the FIR filter model. The DACs serve as programmable current sources for the tail current sources of respective differential pair stages. This innovative approach enables reliable extraction of receive signals from inherent ringing induced by the channel interconnect, achieving higher data rates than previously possible.
