ELCA @ 2021 Huawei Student Design Contest

On the 15th of December 2021, the Huawei Belgium Research Center (BERC) held its yearly Analog/RF Student design contest. In this competition, ten students from the entire Benelux presented their previously published research to an audience consisting of Huawei managers and engineers.
Our Ph.D. candidate, Mohammadreza Beikmirza, proudly represented the ELCA research group and received the first-place award of the contest. Mohammadreza Beikmirza highlighted his innovative 4-way Doherty digital-intensive transmitter. In his breakthrough RFIC chip, a 12-bit 4-way Doherty I/Q digital transmitter featuring a 50% LO signed I/Q interleaved upconverter in 40nm CMOS was presented. His chip achieves 27.5dBm RF peak power at 5.5GHz, while its drain efficiencies at peak and 10-dB back-off are 47% and 40%, respectively. Its intrinsic I/Q image and LO leakage of a 200MHz single-tone signal are better than -62 & -67dBc, respectively, over a 4.5-to-6GHz band. Using a simple DPD when applying a 320MHz 512-QAM OFDM signal, the measured ACLR & EVM are -40dBc & -32dB, respectively. 


EI @ 2021 Huawei Student Design Contest

The Electronic Instrumentation (EI) lab wins two awards at the Huawei 2021 Analog/RF IC Student Design Contest.

Last December 15th the Huawei Belgium Research Center (BERC) held its yearly Analog/RF Student design contest. In the contest, ten students from the entire Benelux presented their previously published research to an audience consisting of Huawei managers and engineers.

Our PhD candidates proudly represented the Electronic Instrumentation Lab and received two awards. Thije Rooijers highlighted his novel technique to reduce intermodulation distortion (IMD) in chopper-stabilized amplifiers which received the Silver Prize (3rd award), while Arthur C. de Oliveira showed how the MEMS Coriolis sensors can be a promising alternative to MEMS Thermal flow sensors in microfluidic applications and got the Golden Prize (2nd award).

 


Altijd geld bij de hand, met een betaalchip onder je huid

In de onstuitbare opmars van het contactloos betalen zet een Pools bedrijf de volgende stap: een betaalchip onder de huid, geen apparaat meer nodig. Wie wil dat? Brigitte heeft er al een. De technologie is echter niet wereldschokkend, zegt Wouter Serdijn, hoogleraar bio-elektronica in Delft. Artikel in de Volkskrant, d. 17 december 2021, door Enith Vlooswijk.

Jan Angevare and Kofi Makinwa, co- recipients of the ISSCC 2021 Takuo Sugano Award for Outstanding Far-East paper

For a paper presented at the 2021 International Solid-State Circuits Conference (ISSCC), the world’s top conference in chip design, members of the Electronic Instrumentation (EI) lab became co-recipients of the Takuo Sugano award for best Far-East paper. During a pre-Covid visit to the TU Delft, Ph.D. candidate Woojun Choi (Yonsei University, Korea) and his counterpart Jan Angevare (TU Delft) came up with the architecture of an integrated frequency reference with high accuracy and low energy consumption, making it well suited for battery-less IoT applications (link to the paper). The resulting chip is just one example of the long and fruitful cooperation between the groups of Youngcheol Chae (Yonsei) and Kofi Makinwa (TU Delft).


ISOCC 2021 ISE President Best Paper Award

At this year's edition of ISOCC 2021, our former excellent bachelor and master student, Jun Feng, obtained the "2021 ISE President Best Paper Award" for his paper: "A Versatile and Efficient 01.-to-11 Gb/s CML Transmitter in 40-nm CMOS."

Ph.D. candidates Mohammadreza Beikmirza and Milad Mehrpoo contributed to Jun's outstanding work. Jun is now a Ph.D. candidate at KU-Leuven. We congratulate Jun, Mohammadreza, and Milad for this award and send our best wishes for their future research.


Best Student Paper Award at ESSCIRC for EI students

The paper “A −109.1 dB/−98 dB THD/THD+N Chopper Class-D Amplifier with >83.7 dB PSRR Over the Entire Audio Band” was selected for the Best Student Paper Award at ESSCIRC 2021 and will be awarded during the 2022 ESSCIRC-ESSDERC Conference in Milan in September 2022. The paper was co-authored by Huajun Zhang, Nuriel Rozsa, Marco Berkhout, and Qinwen Fan, and the work is done in collaboration with Goodix Technology.
