Congratulations, Dr. Ghadami!

Congratulations, Dr. Ghadami!

Omid successfully defended his thesis titled “The Role of CMOS-Enabled Biomedical Devices in Digital Healthcare: from Real-time in-vivo Wireless Sensor Nodes to Biomarker Probe Synthesis.” Omid shared two exciting, highly innovative projects using CMOS chips for electrochemistry. The first, BioMote, is a sub-uW, fully self-contained injectable sensor for continuous analyte monitoring, and the second is a high-density DNA synthesis platform. He has a very impressive body of work, and we wish him all the best in his future endeavors. Congratulations, Dr. Ghadami!

As has become a tradition in our research group, we celebrated with a chip cake.

Congratulations, Dr. Sveiven!

Congratulations, Dr. Sveiven!

It was a big day — Michael successfully defended his thesis titled “Magnetic Biosensors for Immunoassays and Enzymatic Activity Quantification,” and Michael’s first first-author paper was accepted! Michael shared two assays he developed based on giant magnetoresistive (GMR) sensors. The first quantifies two biomarkers relevant to spontaneous preterm birth (link), and the second demonstrates the versatility of real-time enzyme-based release assays. We wish him all the best in his future endeavors. Congratulations, Dr. Sveiven!

As has become a tradition in our research group, we celebrated with a chip cake.

Congratulations, Dr. Pochet!

Corentin successfully defended his thesis titled “Higher-order VCO-based ADCs for sensor interfaces” today. Over the past 6 years, Corentin showed that VCO-based ADCs could achieve performance commiserate with their voltage-mode counterparts. A very impressive body of work, and we wish him all the best in his future endeavors. Congratulations, Dr. Pochet!

As has become a tradition in our research group, we celebrated with a chip cake.

Corentin to present at ISSCC 2022

Corentin will present his work titled “A 4.4µW, 2.5kHz-BW, 92.1dB-SNDR 3rd-Order VCO-based ADC with Pseudo Virtual Ground Feedforward Linearization” at ISSCC this year! This work shows how one can feed forward the pseudo virtual ground in a capacitively coupled VCO-based ADC to linearize and stabilize the system while only using a single feedback DAC. This approach enables a high dynamic range (DR) due to the 3rd-order noise-shaping and >120dB SFDR due to the linearization. The prototype ADC consumes 4.4µW from a 0.8V supply achieving the best-reported SNDR Schreier Figure-of-Merit (FoM) for VCO-based ADCs at 179.6dB.

Congratulations, Corentin!

Congratulations, Dr. Huang!

Chih-Cheng (Iric) successfully defended his thesis titled, “Magnetoresistive Devices for Biosensing Applications” yesterday. We celebrated his achievements with a “chip cake”! (If you are unfamiliar with this tradition, check out this video.)
