Research ArticleOpen accessIn the keywordsLow Power Phase Locked Loop Frequency Synthesizer for 2.4 GHz Band ZigbeeNesreen Mahmoud Hammam Ismail, Masuri OthmanProblem statement: Wireless communication systems are required for many applications. There are different standards for these systems. IEEE 802.15.4 defines the communication system standard for zigbee. This study discussed designing one of the blocks of zigbee transceiver which is the Phase Locked Loop (PLL). A major target for any communication systems is saving battery power, especially for zigbee as it … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 30 Jun 2009 · 8,057 accessesView PDFCite
