The frequency enhancement analysis and design considerations for the both ILFDs are given. The effects of vias and interconnections on the inductance and quality factor are also discussed. Both ILFDs have been fabricated in 65 nm CMOS process. The measured locking ranges of these two ILFDs are 182.7-185.7 GHz and 192.4-194.06 GHz, respectively. © 2012 IEEE.Frequency dividers; ILFD; injection-locked; π-type LC network[SDGs]SDG9CMOS integrated circuits; Resonant circuits; Design considerations; Frequency dividers; High frequency HF; ILFD; Injection locked; Injection locked frequency divider; Locking range; Quality factors; Frequency dividing circuitsjournal article10.1109/TCSI.2011.21624622-s2.0-84856502402WOS:000304398600009
