Latest Patents

Nang Ping Tu's latest patents include two groundbreaking inventions. The first patent is titled "Systems and methods providing active and passive charge sharing in a digital to analog converter." This method involves converting a multi-bit digital value to an analog value through a two-step process. In the first conversion cycle, a first set of digital bits is converted to a first analog voltage using passive charge-sharing. In the second cycle, a second set of digital bits is converted to a second analog voltage, which is added to the first analog voltage using active charge-sharing. This innovative approach enhances the efficiency of digital to analog conversion.

The second patent is for a "Method for preventing the over-stress of MV devices." This invention includes a device with a first power supply line carrying a first positive power supply voltage and a second power supply line carrying a lower second positive power supply voltage. The device features a protection circuit that incorporates a MOS transistor and a diode, which are serially coupled between the two power supply lines. This design ensures that the diode is forward biased by both positive power supply voltages, providing effective protection against over-stress.
