Title: Shigenobu Satoh: Innovator in Integrated Logic Circuits
Introduction
Shigenobu Satoh is a prominent inventor based in Kawasaki, Japan. He has made significant contributions to the field of integrated logic circuits, holding a total of 2 patents. His work has been instrumental in advancing technology within this domain.
Latest Patents
One of Shigenobu Satoh's latest patents is focused on an integrated logic circuit and a hierarchical design method. This innovation involves modules disposed in a chip, which include a plurality of external buffer cells located along the module's periphery. An internal circuit is situated inside these external buffer cells. The design allows for input and output of signals between the internal circuit and the external circuit through the external buffer cells. Notably, the output-stage transistor of each external buffer cell is larger than the transistor size of the internal circuit. The external buffer cells possess the capability to drive a transistor inside the chip directly through a wire, accommodating the maximum Manhattan length of a module-disposed region on the chip. If the area for the external buffer cells is insufficient, the module size can be enlarged, or repartitioning can be performed to ensure adequate space for the external buffer cells.
