Welcome to WICS Lab

Wireless Integrated Circuits and Systems Lab (WICS Lab) develops innovative and energy efficient RF/analog circuits and systems for real world applications in wireless communication, energy harvester, and sensor interface.

WICS Lab, led by Prof. Kuang-Wei Cheng, explores the techniques to enhance the energy efficiency in RF/analog and mixed-signal integrated circuits and systems. Our research focuses on the area of (I) ultra-low-power RF front-end circuits and energy efficient wireless transceivers, (II) low power techniques for analog-to-digital converter (ADC) and phase locked-loop (PLL), (III) wireless powering and energy harvesting circuits, and (IV) bio-medical and sensor interface.
