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 verified...

This paper presents a method for increasing the operating frequency range of sub-6 GHz transmitter to millimetre wave (mm-wave) using two cascaded doublers. The usage such up-conversion approach is constrained since applying first doubler’s generated harmonics second doubler mm-wave signal creation, results in severe distortions and bandwidth expansion transmitted signal, limiting use method. W...

Wideband and frequency-tunable microwave signal generation using an optoelectronic oscillator incorporating a Fabry-Perot laser diode (FP-LD) with external optical injection is proposed and demonstrated. Through external injection, the FP-LD functions as a tunable high-Q photonic microwave filter, and the frequency tuning is realized by either tuning the wavelength of the externally injected op...

In this paper, a novel extended permanent magnet synchronous motor model is presented that incorporates quadratic flux-current function to represent the polarity-dependent saliency. The proposed enables design of sensorless polarity detection algorithms required by initial position motors. novelty it integrates saliency into traditional machine and introduces new parameter, coefficient, specify...
