Latest Patents

Feng Su's latest patent is titled "N-stage exponential charge pumps, charging stages therefor and methods of operation thereof." This innovative design utilizes a series of identical or similar charging stages, each equipped with a first and second capacitor. During the first clock phase, the first capacitor of each stage is charged by the second capacitor of the preceding stage. In the complementary second clock phase, the positive plate of the first capacitor is pushed to an increased voltage, which simultaneously charges the second capacitor of the next stage. This mechanism is mirrored in the second capacitors, ensuring efficient voltage management. The increased voltage from the last stage's capacitors is then pumped to an output capacitor during their respective clock phases.
