摘要
现代无线通信要求频率综合器同时满足快速切换时间,小信道宽度和低噪声性能三方面的要求。分数N频率综合器在这方面的优良特性使得它在现代无线通信系统中被广泛使用。文章系统地讨论了用CMOS工艺实现分数频率综合器的技术问题,并对频率综合器的发展方向和面临的挑战提出了一些看法。
Modern wireless communication requires that the frequency synthesizer should have fast settling time,small channel width and low phase noise. Fractional-N frequency synthesizer is widely used due to its excellent performance in these aspects. Design techniques for CMOS Fractional-N frequency synthesizers are systematically discussed in the paper. Finally, the research direction of the frequency synthesizer, as well as challenges in the development, is analyzed in brief.
