Latest Patents

Hisami Saitou's latest patents include an analog-to-digital converter, an analog-to-digital conversion method, and an optically coupled insulating device. The analog-to-digital converter features a first switch circuit that receives an external analog signal and outputs it in both reverse and positive phases. It also includes a first integrator that integrates the analog signal with cross-coupling, a second switch circuit, and a quantizer that single-bit-quantizes the output to provide a digital signal. The digital-to-analog converter then receives this output and provides it as an analog signal.

The optical receiver circuit and optical coupling device consist of a light-receiving element and a transimpedance amplifier (TIA) that outputs a voltage signal in response to a current signal. This system also includes multiple voltage sources for reference voltages, a level shift circuit, and a comparator that converts the voltage signal to a pulse. The controller manages the output of the shift control signal based on the voltage levels.
