This work concerns with the design and analysis of phase locked loops (PLLs). In the last decade a lot of works have been done about the analysis of PLLs. The phase locked loops are analyzed briefly, second order, third order, and fourth order. In practically the design of 1.3 GHz, 1.9V second order PLL is considered. SPICE simulation program results confirm the theory. Key-Words: Phase Locked ...

A high-speed triangular-modulated spread-spectrum clock generator using a fractional phase-locked loop is presented. The fractional division is implemented by a nested fractional topology, which is constructed from a dual-modulus divide-by-(N–1/16)/N divider to divide the VCO outputs as a first division period and a fractional control circuit to establish a second division period to cause the o...

A novel three-phase phase-locked loop solution is proposed based on D-Q transformation aiming at the AC-DC rectifier with high efficiency and high power factor. The phase-locked loop is implemented digitally using the Xilinx blockset integrated with Matlab/Simulink. The three-phase digital phase-locked loop (TDPLL) is elaborately designed with the parameters defined in detail. The AC-DC convert...

We discuss the phase structure and fluctuations of conserved charges in two flavor QCD. The importance of the density fluctuations to probe the existence of the critical end point is summarized. The role of these fluctuations to identify the first order phase transition in the presence of spinodal phase separation is also discussed.

In previous work, we have shown that second-order phase locked loop (PLL) with sinusoidal phase detector characteristics have a separatrix cycle for a certain value of closed loop gain. It was verified that bifurcation from a stable separatrix cycle is the mechanism responsible for breaking the limit cycle associated with the PLL’s out-of lock state and the loop pulls in (phase lock). The value...

High-speed links which employ source synchronous clocking architectures have the ability to track correlated jitter between clock and data channels up to high frequencies. However, system timing margins are degraded by channel skew between clock and data signals and high-frequency loss. This paper describes how these key channel effects impact the jitter performance and influence the clocking a...

The standards governing the grid connection of distributed power generation systems (DPGS) are becoming increasingly demanding due to the growing number of alternative energies being connected to the grid. Grid connection standards now place greater emphasis on the fault ride-through capabilities of the DPGS. In order to fulfill these standards, improvements must be made to the grid-side contro...

A 0.5–5 GHz wide-range multiphase delay-locked loop (MDLL) with a calibrated charge pump is presented. A multiperiod-locked technique is used to enhance the input frequency range of a MDLL and avoid the harmonic-locked problem. The charge pump current is also calibrated to reduce the static phase error. This MDLL has been fabricated in 0.13m CMOS process. The measured root-mean-square and peak-...
