Se presentará:
**Matías Jara T.** Ph.D. de la Universidad de California - Los Angeles, Ingeniero de Hardware en Broadcom y Exalumno DIE-PUC con especialización en Microelectrónica.
Título: "A Predictive SAR ADC Architecture".
Abstract: High-speed low-power analog-to-digital converters (ADCs) find application in communication systems and signal processing. The principal challenge in developing such ADCs stems from speed-power-resolution trade-offs. An attractive low-power solution is the successive approximation (SAR) architecture, but it suffers from a low conversion speed.
This work introduces a SAR ADC that employs a predictive technique to increase the conversion speed. In this new technique, the comparator operates in parallel with the logic and DAC, reducing the SAR timing budget per cycle to only one comparator decision time plus its clock generation. Moreover, a clock and input
signal distribution method is presented that improves clock phase matching in a time-interleaved system. This is accomplished by delivering the primary clock to each channel and generating their interleaved phases locally. Realized in 28-nm CMOS technology, a 6-bit 10-GS/s 17.6-mW prototype achieves an SNDR of 31.2 dB at an input frequency of 4.96 GHz and a figure of merit equal to 59 fJ per conversion step.
Short-Bio: Matias Jara received the B.S. and M.S. degree from Pontificia Universidad Catolica de Chile in 2013 and 2016, respectively, and the Ph.D. degree from the University of California at Los Angeles in 2022, all in electrical engineering. He was a Graduate Student Researcher at the Communication Circuits Laboratory at UCLA from 2018 to 2022. Afterwards, he joined Broadcom as a Hardware Engineer in the Physical Layer Products division. His research interests are high-speed analog-todigital converters and analog front ends for wireline transceivers. Dr. Jara was also awarded the top prize of the 2022 SSCS Student Circuit Contest.
