Resonant frequency divider design methodology for dynamic frequency scaling

摘要

A rotary traveling wave oscillator (RTWO) frequency divider design methodology is proposed for dynamic frequency scaling. The proposed methodology can be used for designing dividers for integer division ratios of 3 to 9 within one circuit topology. HSPICE-based experiments are performed to test the electrical characteristics of the RTWO frequency dividers. The simulation results show that the power consumption of a frequency divider is as low as approximately 5mW for different frequency division ratios.
