Latest Patents

Shigemori's latest patents include advancements in comparator technology and analog-to-digital converters. His comparator design focuses on reducing power consumption while improving operational speed. The comparator features a comparing section that outputs the result of a comparison between a first voltage and a second voltage, which constitute an input differential signal. It also includes a first positive feedback section that operates in synchronism with a first clock signal, amplifying the result from the comparing section and outputting the amplified result to an output node pair. Additionally, a second positive feedback section operates in synchronism with a second clock signal, providing positive feedback to the output node pair.

In his A/D converter patent, Shigemori addresses the limitations of conventional A/D converters that require an external input operation clock signal. He introduces a clock generator circuit that automatically generates an operation clock within the A/D converter, eliminating the need for an external clock. This innovation allows for high-speed operation and low power consumption by optimizing the clock generation based on the operation times of the A/D converter's constituents.
