Frequency locking in an injection-locked frequency divider equation
We consider a model for a resonant injection-locked frequency divider, and study analytically the locking onto rational multiples of the driving frequency. We provide explicit formulae for the width of the plateaux appearing in the devil’s staircase structure of the lockings, and in particular show that the largest plateaux correspond to even integer values for the ratio of the frequency of the...

متن کاملA Wide Locking Range Injection Locked Frequency Divider with Quadrature Outputs
This paper presents a quadrature injection locked frequency divider (ILFD) employing tunable active inductors (TAIs), which are used is to extend the locking range and to reduce die area. The CMOS ILFD is based on a new quadrature voltage-controlled oscillator (VCO) with cross-coupled switching pairs and TAI-C tanks, and was fabricated in the 0.18-μm 1P6M CMOS technology. The divide-by-2 LC-tan...
متن کاملA 27.9-53.5-GHz Transformer-Based Injection-Locked Frequency Divider with 62.9% Locking Range
An ultra-wide locking range transformer-based injection-locked frequency divider (ILFD) is presented. By making use of a 4-order transformer-based resonator and an inductive gain peaking technique, the proposed ILFD can achieve high performance in terms of wide locking range and low power consumption. Fabricated in a standard 65nm CMOS process with a core area of 0.18mm, the ILFD measures a loc...
متن کاملAn effective method for the determination of the locking range of an Injection-Locked Frequency Divider
The paper proposes a methodology for the determination of the locking range of an Injection-Locked Frequency Divider. The technique involves the use of the Warped Multi-time scale model and is applicable to oscillators in general. The ability to determine, in an efficient manner, the locking ranges of Injection Locked Frequency Dividers is of great importance to design engineers as ILFDs are su...
