Release Details

Silicon Laboratories' Fellows Program recognizes the highest level of technical achievement and contribution by a Silicon Laboratories engineer. Silicon Laboratories' Fellows are selected based on proven mastery of multiple aspects of mixed-signal design, support for the mentoring and continuing education of the Silicon Laboratories technical team, significant contributions to the company's technology and a considerable, direct impact on business success through technical innovation.

"Tim embodies what we value in a mixed-signal designer -- expert level analog design coupled with an equally strong understanding of digital design and signal processing. Tim has consistently led the design of market-leading products and has also been instrumental in product conception," said Jeff Scott, Fellow and Silicon Laboratories co-founder. "His work ethic, flexibility and willingness to embrace any challenge have set him apart for some time. It is with pleasure that we include this honor to Tim's long list of accomplishments."

Mr. Dupuis joined the company in 1997 and began work on the company's first product, the silicon direct access arrangement (DAA). Mr. Dupuis conceived of the ISOmodem® embedded modem and led the design of this product which has since captured approximately 25 percent market share of set-top boxes. Mr. Dupuis was also part of the design team that developed the first CMOS power amplifier (PA), and he is currently leveraging the RF techniques developed for the PA for advanced products in digital power.

Prior to joining Silicon Laboratories, Mr. Dupuis was a design engineer at Oak Technology where he was the lead on audio product development. Previously he was a design manager at Crystal Semiconductor, a subsidiary of Cirrus Logic, working on delta sigma modulators and audio codecs. He holds a bachelor's degree in electrical engineering from the University of Waterloo in Ontario, Canada. Mr. Dupuis holds more than 40 patents in the area of mixed-signal ICs.
