Best MSc Award 2017 goes to Douwe

On Thursday 30 November Douwe van Willigen received the best MSc award at the Electronic Instrumentation Laboratory. Four students were nominated for their excellent thesis work: Michele D’Urbino, Douwe van Willigen, Shoubhik Karmakar and Said Hussaini. They presented their work at the Electronic Instrumentation Laboratory and the audience voted for the best student of 2017.

Douwe developed a chip that makes it possible to connect 64 small ultrasound transducers to an imaging system using a single coaxial cable. His work enables 3D acoustic imaging from the tip of a catheter and is a step forward in miniaturizing 3D ultrasound probes. After his MSc Douwe continues in Michiel Pertijs’ group as a PhD candidate, working on electronics for ultrasonic flow measurement.


Michele D'Urbino wins the A-SSCC Student Design Contest

The Award Ceronomy at the A-SSCC conference

At the 2017 Asian Solid-State Circuits Conference (A-SSCC), Michele D'Urbino won the Student Design Contest with the paper "An Element-Matched Band-Pass Delta-Sigma ADC for Ultrasound Imaging". Michele worked in Michiel Pertijs' group at the Electronic Instrumentation Lab and obtained his MSc Degree earlier this year.

Michele developed an analog-to-digital converter (ADC) capable of digitizing the signals received by every individual element of a 2D ultrasound transducer array. This is an important step towards the realization of next-generation ultrasound probes with full in-probe digitization of the received echo signals. Michele’s ADC has an record-small element-matched size of 150 μm × 150 μm, which is realized by exploiting each piezo-electric transducer element not only as the signal source, but also as the electro-mechanical loop-filter of a continuous-time band-pass ΔΣ ADC.

A-SSCC is a major IEEE Conference on Integrated Circuit Design, and was held in Seoul on Nov. 6-8. At the conference, Michele gave a live demo of his prototype. This work is a collaboration with Oldelft Ultrasound, and was co-authored by Chao Chen, Zhao Chen, Zu-Yao Chang, Jacco Ponte, Boris Lippe and Michiel Pertijs.

Chao Chen wins Best Student Paper Award

At the 2017 IEEE Ultrasonics Symposium in Washington DC, PhD student Chao Chen has won the Best Student Paper Award. Chao works in Michiel Pertijs’ group at the Electronic Instrumentation Lab on integrated circuits for miniature ultrasound probes, in close collaboration with the Acoustical Wavefield Imaging group at TNW, and the Thoraxcenter at Erasmus MC. Chao’s paper describes a chip that makes it possible to connect 1000’s of small ultrasound transducer elements integrated at the tip of an endoscope or catheter to an imaging system. It represents an important step towards the realization of future miniature 3D ultrasound probes. The International Ultrasonics Symposium is IEEE’s main forum for researchers to present new results and learn about recent advances in medical and industrial ultrasonics.


ESSCIRC 2016 Best Paper Award

On 14th September 2017, Ph.D. student Junfeng Jiang has won the ESSCIRC 2016 Best Paper Award for his paper "A Hybrid Multi-Path CMOS Magnetic Sensor With 76 ppm/°C Sensitivity Drift". Junfeng works in Kofi Makinwa's group at the Electronic Instrumentation Lab on wide bandwidth magnetic sensors for current measurements.
