The Analog VLSI Lab at Oklahoma State University explores the intersection of Analog, Security, and AI. Our research vision is to rein in the skyrocketing computing energy demand (e.g., HPC & AI workload) and address emerging security challenges through circuit-level innovations.

Our educational goal is to cultivate future semiconductor talents in alignment with the Chips and Science Act. We always seek self-motivated students to conduct ground-breaking research toward M.S. and Ph.D. degrees. We also seek industry, government, and educational partners (K-14) to improve semiconductor education and workforce development efforts. 


Research Experience for Teachers (RET) Site

Application Website: https://ceat.okstate.edu/stem/ret/ 

Date:  June 12-June 30, 2023, and July 10-July 28, 2023

Teachers from Oklahoma high schools and community colleges are encouraged to apply! We will start reviewing applicants shortly.

We are proud to receive a grant (#2206941) from the National Science Foundation (NSF) to run a RET Site: Chip Design Experiences for Teachers to Stimulate Semiconductor Education in Oklahoma starting 01/01/2023. Dr. John Hu will be the Principle Investigator (PI). Co-PIs are Dr. James Stine, Dr. Wooyeol Choi, and Dr. Erin Dyke.

Batteryless Energy Harvesting (RAISE)

Team 1: Field Test: Extracting energy using TEG. BLE Radio. Sensors

Team Member (alphabetical order): Anfal Hussain, Aaron J. Sosa, Ryan Vaughan.

A thermoelectric generator (TEG) can harvest energy from the temperature differences between the soil surface and shallow ground. When tested in April in Oklahoma, the TEG generates 10~40 mV of stable DC voltage. Bluetooth Low Energy (BLE) protocol can be used to send data. The relationship between the duty cycle and system power consumption was explored. Moisture & humidity sensors were also implemented.

Batteryless Energy Harvesting (RAISE)

Team 2: DC-DC Boost Converter Design & Test. MCU. Electronics Test

Team Member (alphabetical order): Agustin Garcia, Chester Stubbs, Jame Ming Tan

A flyback ("Boost") converter was designed and tested using a commercial off-the-shelf IC (MCRY12) and 1:50 transformer. It can boost up to 1V of DC voltage when the TEG input voltage is around 20 mV. The Boost converter PCB measures about 0.5 square inches (or 2 cm²), compact enough to be integrated with the TEG and the copper rod.

2021 Kicker Design Competition

ECEN 5363 (Mixed-Signal IC Design) and ECEN 3714 (Network Analysis) held a joint student design contest in Fall 2021. The winners are:

The contest was sponsored and judged by Kicker, a high-performance audio company headquartered in Stillwater, OK.  [More Details]

Nipun received IEEE CASS Travel Grant

Nipun Kaushik has been selected to receive the 2021 IEEE Circuits and Systems Society (CASS) Student Travel Grant.

"The CAS society is especially proud and happy to honor your outstanding accomplishments and we look forward to maintaining future close contact with you in the future." said in the announcement email (4/26) by Amara Amara, IEEE CASS President.

CASS offers Studen Travel Grant awards to enable the winners to present their research work at CASS flagship conferences. Nipun will present his work [IEEE Xplore] in 2021 ISCAS. Congratulations to Nipun!

Our Research at ISCAS 2021

Two of our papers will appear in the SPECIAL SESSION: Design and Detection of Hardware Trojans in Cyber-Physical Systems at the 2021 IEEE International Symposium on Circuits & Systems (ISCAS), to be held in Daegu, Korea. 

Congratulations to Rowshon and Nipun!
