题目：Integrated RF CMOS frequency synthesizers and oscillators for wireless applications
摘要：
PLL (Phase-Locked Loop) frequency synthesizers are used in wireless transceivers for frequency conversion. Recent directions in PLL frequency synthesizer research and development are to fully integrate PLL synthesizers in CMOS technology, to improve phase noise performance, and to operate wide range of frequency bands and channel bandwidths. Fully integration of synthesizers in CMOS technology is desired for low cost, low power consumption and small size in mobile wireless terminals. Low phase noise and high performance are required by digital modulation techniques which have been used in new generations of wireless standards for the efficient use of available frequency spectrum.
