0

AUSTIN, Texas–(BUSINESS WIRE)–John Melanson, senior technical researcher at Cirrus Logic (Nasdaq: CRUS), received his 500e American patent, an achievement that places him among the most prolific inventors in the world. The Academy Award®The main contributions of the winning engineer are in the field of audio and electronics, in particular the analog and mixed-signal technologies that have helped transform the analog world around us into digital signals at the heart of products. most advanced today. Melanson’s contributions have changed the way humans interact with their devices — and each other. In particular, its audio patents are instrumental in many of today’s most popular consumer and professional audio applications. Its patents related to LED lighting have had a positive impact on the environment through significant energy savings.

Melanson’s innovations have also been the catalyst for many products that have led to rapid advances in personal computing, semiconductors and networking. His first patent in 1974 helped make modern keyboards possible, and his underlying work in light-emitting diode electronics allowed LEDs to overtake incandescent lighting in popularity by solving dimming challenges. As a founding member of AudioLogic (later acquired by Cirrus Logic), Melanson pioneered the use of low-power digital signal processors (DSPs) for hearing aids. He also helped develop the first networked distributed audio system, a technology that eventually found its way into the audio cabling of the U.S. Senate and thousands of facilities around the world, such as theme parks and concert halls. .

As a pioneer of professional and consumer audio equipment, it received an Oscar® award from the Academy of Motion Picture Arts and Sciences in 2004 for his groundbreaking contributions to the evolution of digital audio editing for film post-production. He also developed the first 500-watt Class-D amplifier for professional audio applications, and his work in developing and implementing algorithms contributed to the active noise cancellation found today. in many smartphones and laptops.

Melanson’s career includes nearly 30 years at Cirrus Logic, where he helped harness computing/processing power and power-saving techniques for today’s personal mobile devices and professional audio and advanced mobile. Its 500e The issued U.S. patent titled “Driver Circuitry and Operation” was granted on June 21, 2022. Additionally, Melanson has 68 pending U.S. patent applications.

“Working at Cirrus Logic gave me the perfect context for creativity and invention,” Melanson said. “The power reduction invention for hearing aids, which I worked on in the 1990s, appears in every Cirrus Logic product we make or at least some of its great-great-grandchildren. loves being able to get involved with technology on a deep level and work on cool stuff while mentoring the folks at Cirrus Logic to keep the company’s spirit of innovation going.
