Wide-division-range high-speed fully programmable frequency divider

This paper presents the design and implementation of an all-programmable frequency divider with an ultra-wide division range for use in phase-locked loops. The proposed divider uses a fully modular architecture and dynamic logic - implemented in TSMC 0.18 mum - and can divide input frequencies up to 7.55 GHz by any ratio between 8 and 255 while consuming 11 mW from a 1.8 V power supply. The divider compares very favorably to other implementations reported in literature in terms of division range and frequency of operation.
