Mission
Our research explores the intersection of Analog, Security, and AI. We rethink what is possible in energy efficiency, performance, and cyber security for future AI, cognition, and ubiquitous computing on a "tiny" chip through circuit and cross-layer innovations.
Analog: Power and thermal management for 3D heterogeneous integration (3DHI), radiation-hardened by design (RHBD) mixed-signal circuits
Hardware Security: Power/EM side-channel security for cryptographic, analog-to-digital converters (ADC), and neural network accelerators
AI and Machine Learning: Analog computing (compute-in-X: SRAM, RRAM), ML-based side-channel analysis
Our educational goal is an all-inclusive semiconductor talent cultivation inspired by the Chips and Science Act. We are eager to collaborate with industry, government, and K-14 partners to improve our nation's semiconductor workforce development.
[Prospective Students] We are always looking for highly motivated students! See here for more details...

Research Experience for Teachers (RET) on Chip Design
Program Website: https://ceat.okstate.edu/stem/ret/
Date: June 12-June 30, 2023, and July 10-July 28, 2023
The 2023 camp is complete. Ten teachers from all around Oklahoma (Stillwater, Cushing, Kingfisher, and Oklahoma City) participated in our program. Four of the teachers presented their research in the 2023 NSF RET Virtual Poster Session of ASEE.

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.
