Purdue Team wins Best Paper Award at CICC Conference
ECE student Baibhab Chatterjee, representing a team from Purdue, received the Best Paper Award at the 2019 IEEE Custom Integrated Circuits Conference (CICC), held April 14-April 18 in Austin, Texas.
This is a joint work advised by Prof. Shreyas Sen, in collaboration with a team advised by Prof. Dimitrios Peroulis and Landauer, a global leader in occupational dosimetry. The paper is titled “A Wearable Real-time CMOS Dosimeter with Integrated Zero-bias Floating-Gate Sensor and an 861nW 18-bit Energy-Resolution Scalable Time-based Radiation to Digital Converter” and the authors are Baibhab Chatterjee, Charilaos Mousoulis, Shovan Maity, Anurag Kumar, Sean Scott, Daniel Valentino, Dimitrios Peroulis and Shreyas Sen.
The paper presented the first monolithic CMOS radiation to digital converter, which consists of a floating-gate radiation sensor and a time-based resistance-to-digital-converter (RDC). The time-based RDC exhibits in-field resolution-energy scalability by controlling the total integrated time for measurement. Time-based sensing provides high-resolution (18 bit) by utilizing the availability of time, for extra low-frequency (ELF) application with ultra-low power (861nW). This research will enable wearable devices for real-time sensing of radiation exposure, for example in scenarios involving healthcare workers in a hospital setting during medical procedures (e.g. Chest CT-SCAN).
The IEEE Custom Integrated Circuits Conference (CICC) is a premier conference devoted to IC development. The conference program includes oral presentations, exhibits, panels and forums. The conference sessions present original first published technical work and innovative circuit techniques that tackle practical problems. CICC is the conference to find out how to solve design problems, improve circuit design techniques, get exposure to new technology areas, and network with peers, authors and industry experts.
Baibhab Chatterjee is a 2nd year PhD student and Andrews Fellow in SPARC Lab. He is also the recipient of the 2018 HOST Best Poster Award.
