Capacitive load balancing for mobius implementation of standing wave oscillator

Resonant clocking technologies are the next generation clocking technologies with GHz range frequency generation and effective power reduction features. The resonant standing wave oscillator technology (with mobius implementation) combines the advantages of resonant traveling wave oscillator and the traditional resonant standing wave oscillator. The high frequency in the mobius standing wave oscillator implementation is often susceptible to implementation parameters such as the variation in the total capacitive load distribution between the rings topology. In this paper, a novel capacitive load balancing methodology is presented for the mobius implementation of resonant standing wave oscillator. The experiments performed on the IBM R1-R5 benchmark circuits demonstrate an average improvement of 4.66X in capacitive load balancing.
