Latest Patents
One of Kun-Wei Chang's latest patents is a "Power switch embedded in ESD PAD." This invention features a driver circuit that utilizes a pad for programming a core circuit or receiving data signals. The design includes a trace high circuit that outputs a voltage approximating a higher voltage of the pad voltage signal and the power supply voltage. Additionally, it incorporates a level shifter and inverter to generate a pull high control signal, along with an ESD blocking circuit that selectively blocks the pad voltage signal from reaching the core circuit.
Another notable patent is the "High-voltage selecting circuit which can generate an output voltage without a voltage drop." This circuit generates an output voltage without a voltage drop by using an auxiliary NMOS transistor to activate the corresponding PMOS transistor when the input voltage levels are equal. It effectively avoids leakage current by turning off the selecting PMOS transistor when one input voltage is higher than the other, ensuring accurate output voltage generation.
