PhD thesis (Apr 2018): Front-End ASICs for 3-D Ultrasound: From Beamforming to Digitization
Promotor: Michiel Pertijs, Nico de Jong

Expertise: ASICs for medical ultrasound and data converters


Chao Chen received the B.Sc. degree in micro-electronics from Tsinghua University, Beijing, China in 2010, and the M.Sc. (cum laude) and Ph.D. degree in micro-electronics from the Delft University of Technology, Delft, The Netherlands, in 2012 and 2018, respectively. His Ph.D. research topic was front-end application-specified integrated circuit (ASIC) design for 3-D medical ultrasound imaging.

Since 2017, Dr. Chen has been a Senior Analog IC designer with Butterfly Network Inc., Guilford, CT, USA, where he contributed to the development of next-generation ASICs for portable ultrasound. In 2021, he moved back to the Netherlands as a postdoctoral researcher at TU Delft, while continuing to hold a position as Consultant at Butterfly Network. His research interests include integrated circuits for medical imaging, low-power sensor interfaces, and high-resolution data converters.

Dr. Chen has authored and co-authored more than 30 publications and holds 3 US patents. He was a recipient of the Huygens Scholarship in 2011, the ISSCC STGA Award in 2013, the IEEE IUS Best Student Paper Award in 2017, and the Else Kooi Award in 2019. He was also a co-recipient of the A-SSCC 2017 Best Student Paper Award.
