开关电容滤波器是目前在测控和通讯领域应用越来越广泛的一类单片集成器件。本文针对使用可编程开关电容滤波器过程中出现的时钟产生电路的程控调节问题 ,通过理论分析和实验研究提出了一个以MAX0 38为核心的宽带可程控调节的频率合成器。
Switched capacitor filter is a kind of monolithic integrated device that is more and more widely used in the field of measurement, control and communication. In this paper, aiming at the programming problem of the clock generation circuit in the process of using programmable switched capacitor filter, a programmable frequency synthesizer based on MAX038 is proposed.
