Abstract
Embodiments of a millimeter-wave phase-locked loop with an injection-locked frequency divider (ILFD) are generally described herein. Other embodiments may be described and claimed. In some embodiments, the ILFD uses a quarter-wavelength transmission line. A method of calibrating an ILFD is also provided to allow the ILFD to operate at or near the center of its locking range for each of a plurality of VCO oscillating frequency bands.
