Abstract :
The design of a K-band divide-by-5 injection-locked frequency divider (ILFD) with a new injector topology in a 0.18-μm CMOS is proposed. The topology is based on a distributed-element harmonic termination by an open-stub structure connected to the floating source end of the differential injection pair. The simulated results indicate that, by using the distributed-element harmonic termination, the locking range can be improved by over 40 %. The power consumption is 7.4 mW at a supply voltage of 0.7 V, with a very wide locking range of 1.9 GHz. The proposed K-band divide-by-5 ILFD has the outstanding figure-of-merit (FOM) values of 6.4, compared with reported works.
