Superharmonic Injection Locked Oscillators as Low Power Frequency Dividers
نویسندگان
چکیده
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 are also used to build a 1:75mW injection locked frequency divider in the 800MHz frequency range to verify the theory.

Superharmonic Injection-Locked Frequency Dividers
Injection-locked oscillators (ILO’s) are investigated in a new theoretical approach. A first-order differential equation is derived for the noise dynamics of ILO’s. A single-ended injection-locked frequency divider (SILFD) is designed in a 0.5m CMOS technology operating at 1.8 GHz with more than 190 MHz locking range while consuming 3 mW of power. A differential injection-locked frequency divid...
متن کامل0.9mW 7GHz and 1.6mW 60GHz frequency dividers with locking-range enhancement in 0.13µm CMOS
Frequency dividers are key components for frequency synthesis in wireless and wireline communication systems. Among different types of frequency dividers, LC-based injection-locked frequency dividers (ILFDs) feature highfrequency operation at low power consumption, but their locking range is quite narrow due to the high-Q nature of the resonator. Recently, design techniques to enhance the locki...

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...

In this work, time domain analysis is used to solve Adler’s equation in order to obtain the required time, for an oscillator under external injection, reaching the steady-state condition. Mathematical approach has been applied to fully describe the transient of frequency acquisition in injection-locked LC and Ring oscillators considering their time-varying nature. Then, the analysis is verifie...
متن کاملEvaluating the Spectrum of Unlocked Injection Frequency Dividers in Pulling Mode
We study the phenomenon of periodic pulling which occurs in certain integrated microcircuits of relevant interest in applications, namely the injection-locked frequency dividers (ILFDs). They are modelled as second-order driven oscillators working in the subharmonic (secondary) resonance regime, i.e., when the self-oscillating frequency is close (resonant) to an integer submultiple n of the dri...
