Abstract

An ultra-low-power millimeter-wave injection-locked frequency divider (ILFD) based on transformer-feedback and transformer-distribution technique is proposed to operate with a very small injection signal. The proposed ILFD measures a locking range from 60.9GHz to 64.7GHz with -7dBm input power while consuming 440uW, which features the minimum power consumption among all the reported V-band frequency dividers. An interesting injection-saturation phenomenon is also identified and verified by measurement results.
