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-Tunable LC-Based Voltage-Controlled Oscillator Using a Divide-by-N Injection-Locked Frequency Divider
This paper proposes a novel wideband voltage-controlled oscillator (VCO) for multi-band transceivers. The proposed oscillator has a core VCO and a tuning-range extension circuit, which consists of an injection-locked frequency divider (ILFD) and flip flop dividers. The two-stage differential ILFD generates quadrature outputs and realizes two, three, four, and six of divide ratio with very wide ...

متن کامل6.2 GHz 0.5 mW two-dimensional oscillator array-based injection-locked frequency divider in 0.18 μm CMOS
ELECT A new two-dimensional oscillator array-based injection-locked frequency divider is proposed. Instead of using the conventional analogue tuning technique or the one-dimensional delay chain, a two-dimensional array is implemented to digitally and precisely control the total delay in the oscillator core. This makes it possible to achieve a programmable delay, hence attaining potential progra...
متن کاملSuperharmonic Injection Locked Oscillators as Low Power Frequency Dividers
Superharmonic injection locking is investigated in a new theoretical approach. Low power frequency dividers are designed using injection locked oscillators with cascode transistors. The Rockwell 0:5 m CMOS process is used to design a 3mW injection locked frequency divider in the 1800MHz frequency range. A 200MHz maximum locking range is achieved in simulations. 2SC3302 TOSHIBA NPN transistors a...
