Title: Innovations of Yoshitaka Murasaka
Introduction
Yoshitaka Murasaka is a notable inventor based in Hiroshima, Japan. He has made significant contributions to the field of electronics, particularly in the development of analog-to-digital converters and optically coupled insulating devices. With a total of 3 patents, Murasaka's work has had a considerable impact on modern technology.
Latest Patents
Murasaka'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, a second integrator, a quantizer, and a digital-to-analog converter. The quantizer single-bit-quantizes the output of the second integrator, providing a digital signal output. The digital-to-analog converter then converts this output back into an analog signal.
The optically coupled insulating device utilizes a PWM encoder to encode a one-bit binary data signal from a sigma-delta analog-digital converter. This signal is synchronized with a clock signal to produce a pulse width modulation signal, which is transmitted through a light-emitting device and a light detector. The decoder decodes the recovered pulse width modulation signal, allowing for the simultaneous transmission of the clock and data signals in one channel.
