摘要
行为级仿真平台的建立,可以对小数频率综合器的设计提供快速全面的时域仿真.重点分析了2/3多模可编程分频器和MASH结构调制器电路,并给出了一种计算环路滤波器参数的新型工程方法.建立了的Simulink仿真模型,可用于检验电路结构的正确性.
The establishment of behavioral-level system simulation platform can provide the accurate and overall time-domain simulations for Fractional-N Frequency Synthesizers design.It laid special stress on analyzing the 2/3 multi-modulus programmable divider and MASH Σ modulator.A new approach for calculating the parameters of loop filter was given.A set of Simulink circuit modes was designed.These modes structure an integrity Σ Fractional-N Frequency Synthesizers which can be used to predict and verify the circuit topologies in practice.
