Title: Sumihiro Takashima: Innovator in Offset Cancellation and Baud Rate Generation

Introduction

Sumihiro Takashima is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of electronics, particularly in the development of offset cancellation circuits and baud rate generators. With a total of 4 patents to his name, Takashima continues to push the boundaries of innovation in his industry.

Latest Patents

One of Takashima's latest patents is an offset cancel circuit and offset cancel system. This invention includes two terminals, an output terminal, and two intermediate nodes. In its first state, the circuit supplies a potential difference responsive to the difference in potential between the two terminals. It also provides a potential responsive to both the potential difference and a first potential to the output terminal. In its second state, the circuit operates similarly but uses a second potential.

Another notable patent is a low-power baud rate generator that includes two oscillators. The first oscillator generates a first clock signal, while the second oscillator produces a second clock signal with a higher frequency but lower frequency accuracy. The first oscillator employs an external resonator, whereas the second does not. This baud rate generator measures the frequency of the second clock signal using the first clock signal and determines a division ratio to generate a clock signal for serial communication.
