%0 Journal Article %T A Low Power and Small Die-Size Phase Lock Loop Circuit Using Semi-Digital Storage %A Markus Dietl %A Puneet Sareen %J International Journal of Design, Analysis and Tools for Integrated Circuits and Systems %D 2011 %I Solari (HK) Co., Hong Kong %X A conventional low-bandwidth Phase Lock Loop (PLL) requires an external capacitor and a big on-chip ripple capacitor. A new PLL architecture is proposed in this paper, which replaces the large external capacitor in the loop filter by semi-digital storage cells. PVT compensation is achieved using the information stored digitally in the storage cells. Since the total value of the on-chip capacitor is reduced drastically, the proposed PLL architecture has a small chip size and a very low power consumption. The design is validated by a silicon implementation. The proposed architecture can also be extended to the design of high bandwidth PLLs. %K Phase Lock Loop %K low power %K real time clock %K circuit %K electrical engineering %U http://ijdatics.distributedthought.com/current_issues/IJDATICS_02_01_05.pdf
