Abstract

A CMOS 60GHz injection-locked frequency divider (ILFD) is demonstrated in this paper by introducing a wide-frequency-range switching-inductor loaded transformer. With different switching conditions, multi-band operation can be realized to improve the locking range with low power consumption and compact area. The 60GHz ILFD together with the entire divider chain is implemented in 65nm CMOS process with measured frequency range from 60.8 to 67GHz covered by two switching bands that can be utilized in 60GHz PLL design.
