High Speed Delay-Locked Loop for Multiple Clock Phase Generation
In this paper, a high speed delay-locked loop (DLL) architecture ispresented which can be employed in high frequency applications. In order to design the new architecture, a new mixed structure is presented for phase detector (PD) and charge pump (CP) which canbe triggered by double edges of the input signals. In addition, the blind zone is removed due to the elimination of reset signal. Theref...
متن کاملPhase Locked Loop Circuits
1. Definition. A PLL is a feedback system that includes a VCO, phase detector, and low pass filter within its loop. Its purpose is to force the VCO to replicate and track the frequency and phase at the input when in lock. The PLL is a control system allowing one oscillator to track with another. It is possible to have a phase offset between input and output, but when locked, the frequencies mus...

متن کاملImpact of - optimization parameters and phase margin on closed loop gain of phase-locked loop
The γ-optimization parameter is one of the key parameters for designing loop filters of phase-locked loop and optimal choice of γ depends on phase margin of the system. Here, we propose to study the impact of γ-optimization parameter and phase margin on closed loop gain of phase-locked loop for frequency synthesizer. A model has been developed and simulated, considering two different filter sec...
متن کاملSoftware Defiend Phase Locked Loop
In this paper a new variety of the digitized version of an analog phase locked loop has been proposed in order to overcome the conditionally stable nature of a software controlled phase locked loop. Also the conventional need of a low pass filter to filter out the high frequency components at the output of a phase detector is avoided through the use of In-phase and Quadrature signals. MATLAB si...
