Abstract:
We propose an all-digital UWB transmitter architecture that exploits the low duty cycle of impulse-radio UWB to achieve ultra-low power consumption. The design supports the IEEE 802.15.4a standard and is demonstrated for its mandatory mode. A digitally controlled oscillator produces the RF carrier between 3 and 10 GHz. It is embedded in a phase-aligned frequency-locked loop that starts up in 2 ns and thus exploits the signal duty cycle that can be as low as 3%. A fully dynamic modulator shapes the BPSK symbols in discrete steps at the 499.2 MHz chip rate as required by the standard. The transmitter can operate in any 499.2 MHz band of the standard between 3.1 and 10 GHz, and the generated signal fulfills the emission spectral mask. The jitter accumulation over a burst is below 6 psRMS, which is within specifications. The transmitter was realized in a 1 V 90 nm digital CMOS technology, and its power consumption drawn from a 1 V supply is from 0.65 mW at 3.1 GHz to 1.4 mW at 10 GHz for a 1 Mb/s data rate.

He received the Ph.D. degree from the same university in 2001, funded by the Belgian national fund for scientific research (FNRS). His doctoral research mainly included joint source-channel coding for image transmissions, focusing on unequal error protection, global optimization of a transmission chain, and image reconstruction from incomplete data. He also worked in channel coding, especially bit error rate approximation for error-correcting codes and code selection for specific applications.
In 2001, he joined IMEC, Leuven, Belgium, to work as a Senior Researcher in the design of ultra-low-power wireless communication systems. He focused on body area networks, developing ultra-wideband solutions and optimizing the power at system level by considering both air interface and front-end architecture. He also has interests in MIMO communications, link adaptation, and turbo coding/processing.
