Design Of High Frequency Digital Phase Locked Loops

چکیده
This paper considers the stability of high order Charge Pump Phase Lock Loop (CP-PLL), proposing a novel means of identifying stable regions for such systems. Traditional design techniques are inefficient for high frequency, high order CPPLL systems. This paper proposes an accurate and efficient means of identifying stable regions for 2 and 3 order high frequency (> 1GHz) CP-PLL. Using exact non-linear CP-PLL responses it is shown that the proposed stability technique is a significant improvement over existing linear methods.

متن کاملDual Phase Detector Based Delay Locked Loop for High Speed Applications
In this paper a new architecture for delay locked loops will be presented. One of problems in phase-frequency detectors (PFD) is static phase offset or reset path delay. The proposed structure decreases the jitter resulted from PFD by switching two PFDs. In this new architecture, a conventional PFD is used before locking of DLL to decrease the amount of phase difference between input and outpu...

Approximating transient response to reasonable specific waveform the loop tran...
متن کاملLow Settling Time All Digital DLL For VHF Application
Settling time is one of the most important parameter in design of DLLs. In this paper we propose a new high speed with low settling time Delay Locked Loop (DLL) in which a digital signal processor (DSP) is used instead of using phase-frequency detector, charge pump and loop filter in conventional DLL. To have better settling time, PRP conjugate gradient algorithm is used to optimize delay of ea...
