Title: Kenji Tanaka: Signal Processing Innovation

Introduction

Kenji Tanaka is an inventor based in Osaka, Japan, and is associated with Nuvoton Technology Corporation Japan. His work includes a patent for a signal processing device and its control method, addressing signal equalization and noise reduction in a re-timer.

Latest Patents

Tanaka is credited with 1 patent: “Signal processing device and control method.” The invention describes a re-timer with a receiver that receives a signal and an equalizer circuit that compensates for signal attenuation. A transmitter sends the received signal and includes a noise-cancelling circuit to reduce noise in the processed signal.

The controller detects the threshold voltage of a transistor in the re-timer and adjusts the equalizer current and noise-cancelling circuit accordingly. When the detected voltage is at or below a predetermined value, the controller limits the equalizer current to a predetermined level or lower and deactivates noise cancellation. When the voltage is above that value, it raises the equalizer current above the predetermined level and activates noise cancellation.

Career Highlights

Tanaka’s patent focuses on adapting signal processing to a transistor’s threshold voltage. This approach coordinates equalization and noise cancellation to support signal transmission under differing operating conditions.

Collaborations

The provided information lists Akinori Shimmyo and Kazuya Hatooka as Tanaka’s coworkers. Their specific roles in the patent or related work are not specified.

Conclusion

Kenji Tanaka’s patent describes a voltage-responsive re-timer that adjusts equalization and noise cancellation, reflecting his contribution to signal processing technology at Nuvoton Technology Corporation Japan.
