基于SystemView仿真的数字频率合成器

Digital Frequency Synthesizer on the Basis of the System View Emulation

介绍了频率合成的原理,常用几种频率合成技术及其优缺点。选择最常用的数字频率合成技术检验其合成频率的效果,在动态系统仿真软件SystemView环境下设计构建了一个数字频率合成器,并对其进行仿真分析,仿真结果表明,在滤波器带宽和VCO的载波最大变化范围内,可产生多个频率稳定的输出信号,达到设计要求。

The paper introduced the theory of the frequency synthesization,it also presented the virtue and defects of some frequency synthesization technology. In order to test the frequency synthesizing effect, the model of a frequency synthesizer was built on the basis of the SystemView emulate. The result indicated that it can produce several output signals with fixed frequency with the permission of the bandwidth of the filter and the max range of the carrier wave of the VCO. And the result obtained the design request.
