Low Power and Low Latency Phase-Frequency Detector in Quantum-Dot Cellular Automata Nanotechnology
Nowadays, one of the most important blocks in telecommunication circuits is the frequency synthesizer and the frequency multipliers. Phase-frequency detectors are the inseparable parts of these circuits. In this paper, it has been attempted to design two new structures for phase-frequency detectors in QCA nanotechnology. The proposed structures have the capability of detecting the phase ...
متن کاملNovel Phase-frequency Detector based on Quantum-dot Cellular Automata Nanotechnology
The electronic industry has grown vastly in recent years, and researchers are trying to minimize circuits delay, occupied area and power consumption as much as possible. In this regard, many technologies have been introduced. Quantum Cellular Automata (QCA) is one of the schemes to design nano-scale digital electronic circuits. This technology has high speed and low power consumption, and occup...
متن کاملphase sensetive detector
phase sensitive detector described here has two principal applications: a- to produce a d.c out put proportional to- the amplitude of an incoming a,c signal and indicate, by the outut polarity, the phase of the signal with respect to an internal reference. b- to detect the presence of a signal of known phase and frequency which would otherwise be lost in «background noise» and to measure its am...
متن کاملDigital Binary Phase-shift Keyed Signal Detector
We have developed the effective algorithm for detecting digital binary phase-shift keyed signals. This algorithm requires a small number of arithmetic operations over the signal period. It can be relatively easy implemented based on the modern programmable logic devices. It also provides high interference immunity by identifying signal presence when signal-to-noise ratio is much less that its w...
متن کاملPhase 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...
