CIRC Lab
where we create knowledge and spread knowledge
Our research group focuses on integrated circuit (IC) design, particularly for implantable biomedical devices (IMDs). Within IMDs, we develop advanced circuits for wireless power transfer, forward/backward data telemetry, neural stimulation, neural recording, on-chip processing, energy harvesting, and ultrasound-based systems. Beyond IMDs, we are broadly interested in any application that can be realized through IC. We pursue ground-breaking ideas and concepts that redefine conventional circuit topologies and push the boundaries of the field, creating innovative technologies for both academia and industry.
CIRC Lab is led by incoming Prof. Hyun-Su Lee
Research Summary
Circuits and Systems
Design and optimization of circuits and systems, including integrated circuits (ICs), to ensure reliable operation, signal integrity, and efficiency improvement.
Biomedical Devices
Implantable medical devices (IMDs), such as cochlear implants, retinal implants, and deep brain stimulators, are designed for safe, reliable, and efficient operation.
In Vivo Validation
After system design, in vivo validation was conducted to obtain recorded neural data, confirming the functionality and reliability of the proposed systems.
