Latest Patents

One of Hsu's latest patents is a charge pump circuit and method thereof. This invention includes a charging capacitor, a plurality of pumping capacitors, a charging circuit, and a pumping circuit. The charging circuit is designed to charge the charging capacitor during the charging phase, while the pumping circuit couples the charged capacitor to a pumping capacitor to generate an output voltage level based on the potential difference stored in the charging capacitor during the pumping phase.

Another significant patent is for a touch panel. This invention features a panel capacitor, a first capacitor, and a second capacitor. The panel capacitor and the first capacitor are charged and discharged cyclically according to a first phase signal and a second phase signal. This process allows an input voltage associated with the panel capacitor and the first capacitor to be applied to a control circuit. The control circuit then charges and discharges the second capacitor based on the input voltage and a reference voltage, compensating for any differences between them. The capacitance of the panel capacitor can be calculated based on the frequency of charging and discharging the second capacitor.
