A 32nm and 0.9V CMOS Phase-Locked Loop with Leakage Current and Power Supply Noise Compensation
This paper presents two novel compensation circuits for leakage current and power supply noise (PSN) in phase locked loop (PLL) using nanometer CMOS technology. The leakage compensation circuit reduces the leakage current of the charge pump circuit which becomes more serious problem due to the thin gate oxide and small threshold voltage in nanometer CMOS technology and the PSN compensation circ...
متن کاملPhase noise reduction of a semiconductor laser in a composite optical phase-locked loop
Amnon Yariv California Institute of Technology Department of Applied Physics and California Institute of Technology Department of Electrical Engineering 1200 East California Boulevard 128-95 Pasadena, California 91125 Abstract. The bandwidth and residual phase noise of optical phaselocked loops (OPLLs) using semiconductor lasers are typically constrained by the nonuniform frequency modulation r...
متن کاملAdditive Noise Response of a Charge Pump Phase-Locked Loop
The additive noise response of a charge pump phase-locked loop in the synchronous mode of operation has been studied. In order to determine the tracking and noise performances of the loop, mean square values of tracking error and local oscillator phase jitter have been analytically obtained. Analytical results agree well with the simulation results obtained here and elsewhere [3]. The analysis ...
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...
