Latest Patents
One of Hiratsuka's latest patents involves an interface circuit designed for noise removal and detection. This circuit operates by utilizing a low-frequency clock signal generated by a CR oscillation circuit. The detection portion receives a signal VBUS, and a detection signal VBD is processed accordingly. When data transmission is initiated by the signal VBUS, a quartz oscillation circuit provides a high-frequency clock signal CK to facilitate the transmission function. Importantly, the operation-enable signal ENB is not supplied when data transmission is not occurring, which helps to minimize power consumption.
Another significant patent is related to a semiconductor device that features a unique arrangement of circuit elements. This device includes a first semiconductor chip with a first circuit element region, where a first electrode group surrounds a second semiconductor chip. Additionally, a second electrode group is arranged to surround the first electrode group, creating an efficient design that enhances functionality and performance.
