PSyLab is presenting 4 papers at CICC this year!

Two of these papers are the result of collaboration with Professor Shaolan Li’s GAMMA research group which is conducting highly innovative work in data converters, AFEs, and other related research.

Jung-Jin Park (JJ) will be presenting his work on the design of highly energy-efficient GPS baseband correlators.  Satellite acquisition incurs a large energy penalty in GPS receivers and JJ will be presenting an energy-efficient approach involving adaptive compressive sampling to take advantage of non-worst case signal conditions (frequently experienced) to severely reduce the required computation in GPS. 

 Arindam will be presenting his multiplexed front end neural signal recording system. This work, done in close collaboration with Professor Shaolan Li, presents a  system that builds upon the group’s prior contribution to the field – multiplexed neural recording front ends – that enables high-density recording. Arindam advances this theme with the design of a highly process technology scalable AFE (incremental delta-sigma with range extension), and shows online calibration that relies on a run-time solver.

The design of both chips presented numberous challenges (and learning opportunities) for the group. We’re thrilled and grateful at the positive outcome of this work.

PSyLab is presenting 2 papers at ISSCC this year!

Hikmet (Seha) Ozturk will be presenting a paper describing a computationally inspired approach to designing accurate, highly compact CMOS thermal sensors which can withstand supply-voltage noise and operate reliably over a wide voltage range. The work is based on ideas in sensor fusion and Principal Component Analysis (Yes, it’s still a circuits paper 🙂 ).

Julian will be presenting his work on a Digitally Reconfigurable IVR (DRIVR) fabric that presents one approach to overcoming the challenge in IVR – how can we build efficient IVRs that can scale to the number of domains in modern SoCs and in emerging 3DHI systems? The approach is based on important insights on Thermal Design Power, and addresses important challenges with run-time reconfigurability such as on-the-fly module-domain assignment. The paper also demonstrates the first known fused-control hierarchical IVR architecture.

I’m especially proud and heartened by how every single member of the group rallied around them to help them mount successful test chips, and ISSCC submissions, even as they were busy with their own projects.

Arindam successfully defended his PhD dissertation this week. He is off to new adventures at Nvidia later this summer!

A number of his labmates missed out on being in-person at his defense, though they did dial in. Arindam has had a remarkable journey in the 6 years he was with us, faced with a formidable problem that he worked on. I’m happy to report that he persevered spectacularly, and concluded his time with us with some truly excellent work. Arindam may be a person of a few words, but he’s been a wonderful student and labmate to have. He will be thoroughly missed, but we look forward to meeting him every now and then through is involvement as a liaison, and at future conferences. All the very best Arindam!

Chi-Hsiang successfully defended his PhD dissertation. He heads off to new adventures at the DDG group at Intel where he will work on next generation circuit technologies. Chi-Hsiang has been a linchpin at PSyLab since he joined us, and a genuine pleasure to be with. He will be thoroughly missed, but we look forward to meeting him every now and then through is involvement as a liaison, and at future conferences. All the very best Chi-Hsiang!
