Latest Patents
Yu David Hu holds a patent for a "Design method for compensation of process variation in CMOS digital input circuits." This invention describes an improved design of CMOS digital input circuits. The improvement reduces the switching level uncertainty range and thus increases the noise margin, compensating for manufacturing process variations. This is achieved by providing resistive compensation devices in series with the P-type and N-type CMOS transistors in the first stage of a multistage digital input circuit. These resistive devices can be implemented by means of resistors or MOSFET devices, which provide the required resistive function. The compensation devices modify the input-output voltage transfer characteristics of the first stage to reduce the switching level variation at the input to the circuit. The resulting digital input circuit has a greater tolerance to input noise levels. This improvement is particularly important as the trend in integrated circuit design is to operate with lower supply voltages. Yu David Hu has 1 patent to his name.
