Latest Patents

Paul Shu Huen Chan holds a patent for an "Asymmetric-amplitude dual-polarity charge pump with four-phase selectable operation." This invention involves a symmetric dual-voltage charge pump and its control circuit, which generates bipolar output voltages. The charge pump is designed to convert a unipolar power source into a set of dual-voltage outputs of opposite polarity that operate independently. The system includes two voltage-boosting transfer capacitors and two output capacitors. The two-phase operation allows for an increased-magnitude output voltage of negative polarity, while another two phases generate an increased output voltage of positive polarity. This innovative charge pump can selectively charge one or both bipolar outputs, enhancing the speed of charge pumping by requiring only two phases for either output.
