## Abstract This article proposes a new CMOS LC‐tank 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 double cross‐coupled CMOS LC‐tank oscillator with a symmetric MOS‐switched LC re
## Abstract In this study, a multimodulus CMOS injection‐locked frequency divider (ILFD) fabricated in a 0.18‐μm CMOS process is designed and the operation principle of the ILFD is described, which was realized using a cross‐coupled PMOS LC‐tank oscillator as the load of a double‐balanced NMOS Gilb
## Abstract A new current‐reused injection‐locked frequency divider is proposed to generate quadrature outputs and implemented using the standard UMC 0.18 μm CMOS 1P6M process. The proposed circuit is made of two LC‐tank voltage controlled oscillators (VCOs) stacked in series and the VCOs are coupl
## Abstract A fourth order resonator has been implemented to design an injection locked frequency divider (ILFD) implemented in a 0.18‐μm CMOS process. The ILFD is realized with a cross‐coupled nMOS LC‐tank oscillator with a direct injection MOSFET and two series‐LC resonators. At the supply voltag
