Phase-locked loops are widely used for synchronization purposes; in space communications for coherent demodulation and threshold extension, bit synchronization, and symbol synchronization. Phase-locked loops can also be used to demodulate frequency-modulated signals. In radio transmitters, a PLL is used to synthesize new frequencies which are a multiple of a reference freque… WebbThe in-band phase noise of the PLL was −129.2 and −132.5 dBc/Hz at 1- and 5-MHz offset frequencies. The measured reference spur of the PLL was −78.1 dBc. Total PLL power consumption was 5.2 mW, resulting in −256.3-dB PLL jitter-power FoM, while occupying 0.17-mm 2 area.
Design of Low Power Phase Locked Loop (PLL) Using 45NM
Webb5 feb. 2024 · Phase-locked loops (PLLs) play a critical role in communications, computing, and data converters. With greater demands for bandwidth efficiency in wireless systems … Webb23 dec. 2010 · If low power consumption is the primary design concern we want to minimize VCO frequency and divide values. Selecting N=3, Q=21, P=220 would be the best choice. This operates the VCO at one of the lower frequencies, lower P and Q values, and has a reasonable PFD frequency. index of epub french
