Latest Patents

One of Nakasuji's latest patents is an optical reception circuit. This circuit includes a first photodetector, a first transimpedance amplifier, a level shift circuit, a second photodetector, a second transimpedance amplifier, a peak hold circuit, and a comparator. The first transimpedance amplifier converts a first light current from the first photodetector to a first voltage. The level shift circuit generates a signal voltage from the first voltage. The second transimpedance amplifier converts the second light current from the second photodetector to a second voltage. The peak hold circuit holds a peak voltage of the second voltage as a first threshold voltage. The comparator then compares the signal voltage with the first threshold voltage.

Another notable patent is the optical-coupling semiconductor device. This device includes a primary support plate and a secondary support plate facing each other and spaced apart by a predetermined distance. A light emitting device is situated on the primary support plate, while a light receiving device includes a light receiving surface to receive light from the light emitting surface of the light emitting device. The configuration ensures that the light emitting device is oriented toward the secondary support plate, allowing for efficient light transfer.
