A novel Phase-Locked Loop scheme is proposed in this paper, whose main distinguishing features are infinite hold-in range, pull-out range fractionally constant and also a ripple fractionally constant. To this end, it incorporates a variable gain amplifer and a frequency tunable loop filter. The driving application is the on-chip automatic tuning of slave filters, although the PLL architecture c...

Technology advances have made gigabit signal a viable and attractive. A method to design IEEE 1394 based 1GHz Phase Locked Loop (PLL) system as frequency synthesizer with Low Phase Noise is proposed. A complementary LC oscillator is used to generate the 1GHz oscillation frequency and is divided into lower frequency clock by the feedback frequency divider. The architecture is type II third order...

A third order Phase locked loop, PLL, is widely used in communication systems. Lately, researcher had found that under certain conditions, such as gain, PLL is experiencing chaotic oscillations. For a single PLL, studies have shown that when the gain of PLL increases, it will encounter a chaotic behavior. To see the mutual effect of two coupled PLL, this paper will derive the mathematical dynam...

The purpose of this work is to explore methods of mitigating the effect of radiation in phase locked loop (PLL) circuits. Several voltage controlled oscillators (VCOs) and ...

This paper presents an integrated frequency hopped transceiver based on a subset of the cdma2000 network specifications. The circuit consists of a phase locked loop (PLL) that generates the hopping carriers, local oscillators (LOs) that generate GHz range carrier frequencies, and a series of mixers. It accepts input data in frequency shift keyed (FSK) format, and also outputs received data in F...

The traditional VSG strategy does not consider the negative sequence component, which will lead to current imbalance and power oscillation under unbalanced voltage. Several improved control strategies of are usable for operating voltage nowadays. These usually require a complex PLL (phase-locked loop) detect components, reference generator convert references references. This paper proposes an V...

Applications of millimeter-wave radar, imaging, and communication technology requires cost-effective implementation of intelligent scanning antenna systems. Injection-locking and phase-locked-loop (PLL) techniques can be used to achieve synchronous operation of a number of antenna array elements, and allow for the manipulation of the phase distribution without additional phase-shifting circuitr...

This paper presents an accurate high level model for the design of sigma-delta fractional Phase locked loop (PLL) architectures. High level models provide simulation speedups of about two orders of magnitude when compared to transistor level simulation. When compared to other models presented in the literature the proposed model has the advantage of having the frequency instead of phase as the ...

This paper presents a complete noise analysis of a ΣΔ-based fractional-N phase-locked loop (PLL) based frequency synthesizer. Rigorous analytical and empirical formulas have been given to model various phase noise sources and spurious components and to predict their impact on the overall synthesizer noise performance. These formulas have been applied to an integrated multiband WLAN frequency sy...

This paper presents a model predictive control (MPC) of a utility interactive (UI) single phase inverter (SPI) for a photovoltaic (PV) system at residential/distribution level. The proposed model uses single-phase phase locked loop (PLL) to synchronize SPI with the grid and performs MPC control in a dq reference frame. SPI model consists of boost converter (BC), maximum power point tracking (MP...
