摘要

A phase-locked loop incorporating a cascade of mixers can provide integer or fractional divide ratios at high frequencies. The circuit topology and its variants are presented, and their advantages over static, dynamic, and injection-locked dividers are described. The effect of nonidealities such as the spurious response and noise of the mixers is also analyzed. A divide-by-two prototype realized in 0.13-$mu$ m CMOS technology operates from 64 GHz to 70 GHz while consuming 6 mW from a 1.2-V supply.
