## Abstract This article studies two wide‐locking range divide‐by‐4 injection locked frequency dividers (ILFDs) employing tunable active inductor (TAI), which are used to extend the locking range and to reduce die area. The CMOS differential ILFD is based on a TAI‐C tank Colpitts voltage‐controlled
## Abstract This article proposes techniques for improving locking range of divide‐by‐4 injection locked frequency divider (D4ILFD). Two D4ILFDs were designed and implemented. One D4ILFD is made of tapped resonator; the other ILFD is made of switched resonator. Both circuits use a complementary CMO
## Abstract This letter proposes a divide‐by‐3 frequency divider employing the linear mixer topology; the divider was fabricated in the 0.35‐μm CMOS 2P4M CMOS technology. The divider consists of an nMOS cross‐coupled LC oscillator and two injection MOSFETs in series with the cross‐coupled nMOSFETs.
## Abstract This study proposes a new divide‐by‐3 CMOS injection locked frequency divider (ILFD) fabricated in a 0.18‐μm CMOS process and describes the operation principle of the ILFD. The ILFD circuit is realized with a Hartley CMOS LC‐tank oscillator with two injection MOSFETs. The self‐oscillati
