Title: Atsuhiro Sengoku: Innovator in Semiconductor Technology
Introduction
Atsuhiro Sengoku is a notable inventor based in Kasugai, Japan. He has made significant contributions to the field of semiconductor technology, holding a total of 4 patents. His work focuses on enhancing the functionality and efficiency of integrated circuits.
Latest Patents
One of his latest patents is a reset signal generation circuit. This circuit generates a reset signal either synchronously or asynchronously to a clock signal based on the operation state. An operation detection circuit is employed to detect the operation of a CPU and generate an operation detection signal. A signal control circuit then generates a first reset signal based on the operation detection signal and a system reset signal, which is provided to synchronous circuits, including the CPU.
Another significant patent is for a semiconductor integrated circuit device with a test circuit that measures a period to select a test mode. This device features a pair of oscillator terminals that provide two oscillation signals with opposite phases. An oscillator circuit supplies a system clock signal based on these oscillation signals. A mode detection circuit identifies when the oscillator terminals receive two input signals with the same phase and sends a detection signal to a test circuit. This test circuit sets a test mode according to the detection signal, providing the internal circuit with a predetermined test signal. This innovation helps prevent an increase in the number of external terminals of the semiconductor integrated circuit device.
