PITT Circuit Lab

PITT Circuit Lab develops energy-efficient sensing and computing systems using application-specific integrated circuit design technique. Also, we use our systems to solve critical problems in fields such as biomedical, infrastructure, energy, ecology, and internet-of-things by collaborating with researchers with expertise in these areas. 

Examples of research topics

• Miniature system development & optimization for target application goals

• Low-power energy-efficient adaptive/reconfigurable analog/digital circuit design

• Ultra-long-lifetime miniature system based on low-power energy harvester

• Energy-efficient power/battery management circuit design
