Latest Patents

One of his latest innovations is the Continuous-time delta-sigma modulator. This device includes a loop filter, a pipelined successive-approximation register analog-to-digital converter (SAR ADC), a feedback circuit, an excess loop delay (ELD) compensation circuit, and a logic circuit. The loop filter generates a first intermediate signal based on an input signal, a feedback signal, and a compensation signal. The pipelined SAR ADC produces a first digital code, a second digital code, and quantization error signals based on the first intermediate signal. The feedback circuit generates the feedback signal according to the digital codes and quantization error signals. The ELD compensation circuit generates the compensation signal based on the feedback circuit's output. Finally, the logic circuit generates an output digital code from the first and second digital codes.

Another notable patent is the clock and data recovery circuit. This circuit comprises a first sampling phase detector and filter circuitry, a frequency detector circuit, a current source circuit, a band controller circuit, and a voltage-controlled oscillator. The first sampling phase detector generates a voltage based on a pair of data and clock signals. The frequency detector produces control signals according to the data and clock signals. The current source circuit generates the voltage based on these control signals. The band controller generates a band control signal based on the voltage, while the voltage-controlled oscillator adjusts the clock signals accordingly.
