Title: The Innovations of Masato Yoshioka

Introduction

Masato Yoshioka is a prominent inventor based in Kawasaki, Japan. He has made significant contributions to the field of electronics, particularly in the development of advanced circuits. With a total of 11 patents to his name, Yoshioka's work has had a considerable impact on technology.

Latest Patents

Yoshioka's latest patents include a gain control circuit and an ultrasonic image device. The gain control circuit features a voltage generation circuit that produces a first voltage that changes linearly over time. It also includes a voltage square circuit that outputs a second voltage obtained by squaring the first voltage. Additionally, a resistance circuit is incorporated, which has a resistance characteristic that changes over time depending on the second voltage. The gain adjustment circuit is designed to adjust gain based on the resistance value of the resistance circuit.

Another notable patent is the AD converter circuit and ad conversion method. This low-power and high-speed ADC consists of a successive approximation converter circuit that sequentially compares and converts the analog input signal voltage into a digital signal. It also outputs a residual voltage. Furthermore, a fixed-quantity change time measurement converter circuit finely converts the residual voltage into a digital signal by changing it at a fixed rate. An encoder circuit generates a digital signal by combining the outputs from both converter circuits.
