Latest Patents

One of his latest patents is titled "Apparatus and method for multi-phase clock calibration in high-speed data communication systems." This invention includes an apparatus for multiphase clock calibration for a transmitter in data communication systems. It features a phase interpolator configured to receive a clock signal and generate multiphase clock signals with adjustable duty cycles and in-phase quadrature control. Additionally, the apparatus includes a pattern generator that generates a pattern output based on a data signal sampled by the multiphase clock signals. A delay-adjust module measures timing differences between the edges of a reference clock and the pattern output with adjustable delays. A phase detector is also included to detect phase errors, while a calibration controller provides controls for adjusting delays to calibrate the multiphase clock signals.

Another notable patent is the "Precision sub-RADIX2 DAC with analog weight based calibration." This system features a sub-binary radix digital-to-analog converter (DAC) that converts a digital input signal to an analog output signal based on a sub-radix DAC code. The radix conversion module performs radix conversion on the digital input signal by associating bit positions with respective analog weights.
