Challenges of calibrated time-interleaved high-speed ADCs

Dr. Aaron Buchwald has 31 years experience in the field of analog integrated circuit design. He is currently a Fellow at Entropic Communications after their acquisition of Mobius Semiconductor, where he was CEO and founder. Prior to founding Mobius Semiconductor, Dr. Buchwald worked at Broadcom, joining as one of the first members of the analog group with the charter to help build a world-class analog team emphasizing design in a mixed-signal environment.

Dr. Buchwald's work on embedded CMOS Analog-to-Digital Converters (ADCs) enabled the production of single-chip cable set-top boxes and cable modems with integrated analog front ends and DSP circuitry. His work was awarded the best paper prize in 1997 at ISSCC. Later, Dr. Buchwald was responsible for development of high-speed serial transceivers (XAUI, CX4 and Fiber Channel) at Broadcom. The initial XAUI transceivers were some of the first to employ adaptive receive equalization.

Dr. Buchwald was formerly an Assistant Professor at the Hong Kong University of Science and Technology (HKUST). In his early career, Dr. Buchwald spent two years as an analog IC designer at Siemens in Munich Germany. Prior to that, he was with Hughes Aircraft Company in El Segundo, CA.

Dr. Aaron Buchwald was born in Ames, Iowa and received a BSEE from the University of Iowa, Iowa City, Iowa, and an M.S. and Ph.D. from the University of California, Los Angeles. He is co-author of the book Integrated Fiber-Optic Receivers. He has taught professional short-courses on data converters and serial transceivers.
