Latest Patents
Kuo-Chung Lee holds a patent for a "Mixed-voltage I/O design with novel floating N-well and gate-tracking circuits." This invention presents a mixed-voltage I/O buffer circuit that effectively prevents leakages through a driver stage PMOS transistor. The buffer circuit features a first part that prevents leakage through a parasitic diode of the transistor and a second part that prevents leakage when the transistor is activated by a signal on a bonding pad with a voltage level higher than the power supply voltage of the buffer circuit. The design ensures that the buffer circuit provides biases approximately equal to the high voltage signal to the gate and substrate terminal of the PMOS transistor when the bonding pad has a high voltage signal, and a bias approximately equal to the power supply voltage when the bonding pad has a low voltage signal.
