Phase Frequency Detector Using Transmission Gates for High Speed Applications
In this paper a new phase-frequency detector is proposed using transmission gates which can detect phase difference less than 500ps. In other word, the proposed Phase-frequency Detector (PFD) can work in frequencies higher than 1.7 GHz, whereas a conventional PFD operates at frequencies less than 1.1 GHz. This new architecture is designed in TSMC 0.13um CMOS Technology. Also, the proposed PFD a...
متن کاملLow Power 0.18um CMOS Phase Frequency Detector
In this paper, the performance of two low power phase frequency detectors is compared. A modified D-FF based PFD reduces the power consumption of traditional PFD to 4.732uW at 40MHz clock frequency and dead zone to 40ps.It is suitable for low power applications. A Falling Edge PFD uses only 12 transistors. This PFD operates up to 1GHz at 1.8V supply voltage. It consumes only 5.5uW when operatin...
متن کاملArea efficient 0 . 18 um Cmos phase frequency detector for high speed Pll
Two phase frequency detectors (PFDs) are proposed in this paper that can overcome the speed and area limitations of conventional PFD. The AND gate based PFD uses 22 transistors. It consumes 161.41uW power when operating at 50MHz clock frequency with 1.8V supply voltage. The NOR gate based PFD uses 20 transistors and preserves the main characteristics of conventional PFD. It consumes 96.67uW pow...
متن کاملA High-Speed, Low-Power Phase Frequency Detector and Charge-Pump Circuits for High Frequency Phase-Locked Loops∗
In this paper, we introduce a high-speed and low-power Phase-Frequency Detector (PFD) that is designed using a modified TSPC (True Single-Phase Clock) positive edge triggered D flip-flop . The proposed PFD has a simple structure with using only 19 transistors. The operation range of this PFD is over 1.4GHz without using additional prescaler circuits. Furthermore, the PFD has a dead zone less th...
متن کاملDesign and Implementation of Low Power Phase Frequency Detector (PFD) for PLL
This paper presents a novel Phase frequency detector for Charge Pump Phase locked loop (PLL) applications to enable fast frequency acquisition in the phaselocked loop (PLL). To cope with the missing edge problem, the proposed PFD predicts the reset signal and blocks the corresponding input signal during the reset time. The blocked edge is regenerated after the reset signal is deactivated [1]. T...
