    Power Efficient, Low Noise 2-5 GHz Phase Locked Loop
    (НТУУ «КПІ», 2011) Melikyan, V. Sh.; Durgaryan, A. A.; Petrosyan, H. P.; Stepanyan, A. G.
    A power and noise efficient solution for phase locked loop (PLL) is presented. A lock detector is implemented to deactivate the PLL components, except the voltage controlled oscil ator (VCO), in the locked state. Signals deactivating/activating the PLL are discussed on system level. The introduced technique significantly saves power and decreases PLL output jitter. As a result whole PLL power consumption and output noise decreased about 35-38% in expense of approximately 17% area overhead.
