摘　　要：应用 PSPICE及采用 C语言自编的外部程序 ,对单片数字锁相环中衬底噪声耦合及衬底噪声对电路性能的影响进行了模拟和分析 ,有助于进一步理解衬底噪声以及衬底噪声对复杂的混合信号电路工作的影响。Substrate crosstalk in the mixed signal IC and its effect on the analog/digital circuits are investigated based on PSPICE simulator and using two external programs written by the authors in C language. The study provides a greater insight into the effect of substrate crosstalk on a complex mixed signal circuit. Proper substrate type and crosstalk reduction technique for applications are proposed in the paper.
