Pspice仿真报告(串并联振荡电路分析)解析

1、第三次高频电子线路小班课Pspice电路仿真实验报告此处为校徽研究题目：串并联振荡电路分析班级：电子信息工程1402班组别：第六组 组员:主讲人* :仿真运行* : PPT制作文档整理仿真实验题目:6将第4题中R1的电阻值改为4K，试观察振荡电路输出波形，此时将电阻R2改为具有负温度系数的热敏电阻，（设此电阻值仍为10K，随温度呈线性变化关系，在电阻模型参数中取Tc仁0.13）,设电路工作在28度，再次分析电路，记录输出波形，并分析原因。热敏电阻值的计算:R2二FEs=R*r*1+Tc1*(T-T0)+Tc2*(TT0)*2=10*1*1 -0.13*(28-27)=8.7K环路增益：T (w
