Resonant clocking technologies
Resonant clocking is a low power clock generation and distribution solution for modern ICs. The main research focus is the design and implementation of rotary clocks that is interoperable within the traditional ASIC flow. Based on years of development and experience within Dr. Taskin's research group numerous products for rotary clocks are currently being developed to address future needs for energy efficient computing.

1. RotaSYN: Rotary Traveling Wave Oscillator SYNthesizer

RotaSYN is a backend synthesis tool for rotary clocks. RotaSYN is demonstrated on publicly available designs and compared to traditionally clocked designs. Check out our RotaSYN PAPER published in TCAS-I.
