Abstract :
A low-jitter LC-based clock distribution in 0.13μm CMOS uses a frequency-tuning technique based on a voltage-swing digitizer. Optimum jitter performance is achieved by adaptively adjusting the injection-lock ratio. The efficiency of this technique results in 25% power-savings in the clock buffer for similar or better jitter performance.
