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...

the aim of this paper is to minimize output phase noise for the pure signal synthesis in the frequency synthesizers. for this purpose, first, an exact mathematical model of phase locked loop (pll) based frequency synthesizer is described and analyzed. then, an exact closed-form formula in terms of synthesizer bandwidth and total output phase noise is extracted. based on this formula, the phase ...

Objective Using Peer Support in Developing Empowering Mental Health Services (UPSIDES) is evaluating implementation of a peer support worker (PSW) intervention at six recruiting sites (Germany, India, Israel, Tanzania, and Uganda) (ISRCTN26008944). The aim this study to evaluate the pre-trial pilot phase.Method initial training prepare individuals for PSW role (PS) was evaluated using multi-met...
