Abstract

An innovative injection-locked frequency divider (ILFD) with transformer transconductance (g_m)-boosted technique is proposed in this paper. By using the g_m-boosted technique to enhance the effective gm, the locking range of the ILFD can be further increased. The proposed ILFD was implemented in 0.18 μm CMOS process. The measured locking range is from 24.6 to 27 GHz, for a locking range of 2.4 GHz, without varactor tuning. The output power is higher than ±11 dBm, and the core DC power consumption is only 2 mW.
