## 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 presents a new low power and wide‐locking range divide‐by‐2 injection‐locked frequency divider (ILFD). The ILFD consists of a new 5.35 GHz quadrature voltage controlled oscillator (QVCO) and two NMOS switches, which are in parallel with the QVCO resonators for signal injecti
