Abstract
A divide-by-4 injection-locked frequency divider (ILFD) is realized in a 90 nm CMOS process. By using the coupled inductors, the locking range of the proposed divide-by-4 ILFD is enhanced. This ILFD has a measured locking range of 125.7-131.9 GHz. Its power consumption is 3.6 mW for a supply of 1.2 V. To the authors´ best knowledge, this is the first CMOS divide-by-4 ILFD operated over 130 GHz.
