| Summary: | 碩士 === 淡江大學 === 電機工程學系碩士在職專班 === 95 === The Low-Power High-Speed Low-Noise PLL is a significant circuit for portable consumer devices. There are many sorts of PLLs due to its huge market demand. Its main applications are portable phones and GPS devices. It requires low-power for allowing the battery has long-used time. Also it demands fast-download speed for text transmission or graphic transmission. Furthermore, it needs low-noise quality to assure excellent sound received quality.
PFD_CP_SC_PLL can reach 4 Giga Hz, 1.47E-02 Watts, and 6.9E-19 SQ V/HZ composed by a Phase Frequency Detector, a Chare Pump Filter, a Source Couple VCO and a 64 Divider. This thesis offers a complete low-power, high-speed, and low-noise PFDCPSC PLL design concept and detailed circuits, allowing communication designers to have a great reference.
