Title: **Shigetoshi Nakao: Innovator in Delta-Sigma Modulation**
Introduction
Shigetoshi Nakao, based in Komae, Japan, is a notable inventor recognized for his contributions to the field of electronics, particularly in the area of delta-sigma modulation. With a keen focus on enhancing signal processing methods, his work has paved the way for more efficient digital-to-analog conversion technologies.
Latest Patents
Nakao holds a significant patent related to DC dither circuitry and method for delta-sigma modulators. This innovation addresses a common challenge in delta-sigma analog-to-digital converters by shifting characteristic tones out of the audible pass band. The technique ensures that dynamic range and signal-to-noise ratios remain intact by measuring the offset voltage of the digital-to-analog converter. If the offset exceeds a predetermined value, dither signals are not applied; however, when under that threshold, appropriate dither voltages are added or subtracted based on the measured offset, enhancing overall performance.
