A low-power programmable DLL-based clock generator with wide-range anti-harmonic lock

A delay-locked loop (DLL)-based clock generator for dynamic frequency scaling has been developed in a 0.13um CMOS technology. The proposed clock generator can generate a wide-range of the multiplied clock signals ranging from 125MHz to 2GHz. In addition, thanks to the proposed anti-harmonic lock block, the clock generator can change the frequency dynamically in one cycle time of the reference clock. The proposed DLL-based clock generator occupies 0.019mm2 and consumes 21mW at 2GHz. The ratio of power consumption to frequency of the proposed clock generator is smaller than those of conventional ones. ©2009 IEEE.
