Latest Patents
Among his latest patents, one notable invention is focused on incremental delta modulation for analog to digital converter signal to noise ratio and linearity enhancement. This device, which can be implemented as a SAR ADC (Successive Approximation Register Analog to Digital Converter), incorporates a Digital-to-Analog Converter (DAC) circuit. It generates a digital output utilizing logic circuitry that includes SAR logic along with delta modulation and dynamic element matching circuitry. The delta modulation circuitry outputs several digital signals from the SAR DAC, while the dynamic element matching circuitry selects diverse capacitor sets from the DAC circuit. These components work together to average inputs over each cycle, enhancing the digital output derived from SAR logic.
Another significant patent addresses systems, apparatuses, and methods for a ping-pong charge pump. This invention highlights an innovative approach to the operation of flying capacitors in ping-pong charge pumps, which are manipulated out of phase. Such an arrangement improves equalization periods and minimizes voltage discrepancies between the flying capacitors, ultimately reducing output voltage ripple and snapback. The design cleverly eliminates the need for an equalization switch, relying instead on differential control currents based on the voltage differences to manage the output load effectively. Furthermore, the flying capacitors experience equalization during the overlapping time while charging, ensuring efficient functionality.
