Biography

Baptiste Grave received the engineering diploma from ISEN Lille (Institut Supérieur de l’Électronique et du Numérique), France, in 2009 and his PhD degree in electrical engineering from the University of Lille, France in 2013. He also took part of the Integrated Circuits Design group at IEMN (Institut d’Électronique, de Micro-électronique et de Nanotechnologies) in Lille. He is now a postdoctoral research associate in Stanford University to develop D-band high data rate communication systems. His research interests concern system level studies and IC design for ultra-high-speed data links.


PhD Thesis : Subsampling Techniques applied to  60GHz receivers in 28 nm CMOS.

Advisor: Andreas Kaiser / Co-advisor: Antoine Frappé

60 GHz radio is the most promising candidate for high data rate short range wireless communications targeting the delivery of uncompressed high-definition video and fast downloading. My thesis focuses on wireless receivers for 60 GHz wireless communications.

A particular arrangement of the frequency plan allows embedded anti-alias filtering. Downconversion, channel filtering and IQ demodulation are merged into a unique operation at no extra cost in terms of area and power consumption. The adjacent and alternate channel rejections for the 802.15.3.c are respectively more than 15 dBc and 23 dBc thanks to charge domain subsamplers.

The first part of my thesis work is an advanced analysis of the system for critical points of the architecture: generation of the integration windows, IQ demodulation, noise folding and effect of clock jitter. The proposed architecture is validated by simulations and complies with the requirements of the standard for 60 GHz wireless communications. The result of this study shows that sub-sampling is suitable for high bandwidth and high data-rate receiver systems.
