Abstract

A 53-67 GHz wide locking range injection-locked frequency divider (ILFD) has been designed and fabricated using 0.13-μm CMOS process.By using forward body bias technique, the proposed ILFD demonstrates good performance of the wide locking range while maintaining low DC power consumption. Via a 0 dBm incident signal power, an input locking rage greater than 14 GHz (>23%) is achieved with 4 mW from supply voltage of 0.8 V. If the supply voltage further reduces to 0.6 V, the input locking rage is 6 GHz (10%) while consuming only 1.2 mW. Compared to previous reported works in high-speed CMOS FD, the presented ILFD achieves superior figure of merit (FOM). Without extra voltage control mechanisms to increase the locking range, this FD covers whole 57-64 GHz band is suitable for integration into a 60 GHz WPAN phase-locked loop system. © 2011 Wiley Periodicals, Inc.
