Transformative scalable systems, such as massive MIMO communication or dense ad-hoc wireless sensor networks (WSN), require reconfigurable and scalable RF systems with graceful tradeoffs between power and performance. Our research addresses these challenges by focusing on co-design of active and passive RF devices/circuits at the two ends of these tradeoffs – ultra low-power for dense sensor-networks and high performance for scalable, reconfigurable RF/mm-wave arrays.
