Latest Patents
Yet Hei Lam holds a patent for "N-stage exponential charge pumps, charging stages therefor and methods of operation thereof." This invention involves an exponential charge pump that utilizes multiple identical or similar charging stages. Each stage consists of 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 of each stage is elevated to an increased voltage by the first capacitor of the preceding stage. This process simultaneously charges the second capacitor of the next stage to the increased voltage. A similar mechanism is applied to the second capacitors in each stage, but with complementary timing. The increased voltage from the first capacitor of the last stage is pumped to an output capacitor during the second clock phase, while the increased voltage from the second capacitor of the last stage is pumped to an output capacitor during the first clock phase.
