Pspice仿真报告(串并联振荡电路分析).doc

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1、 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Tc1=-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。图PSP-1-（1）热敏电阻值的计算：R2=RES=R*r*1+Tc1*(T-T0)+Tc2*(T-T0)*2=10*1*1-0.13*(28-27)=8.7K环路增益：T（w0）=(R1+R2) / 3R1二仿真电路原理图：图PSP-2-（1）3 参数 图PSP-3-（1）输入文件图PSP-3-（2）图PSP-3-（3）四 代码：* 11/03/16 23:11:30 * PSpice 10.5.0 (Jan 2005) * ID# 0 * * Profile: SCHEMATIC1-DCSweep F:pspice jinshzuhen-pspicefilesschematic1dcsweep.sim * CIRCUIT DESCRIPTION* Creating circuit file DCSweep.cir * WARNING: THIS AUTOMATICALLY GENERATED FILE MAY BE OVERWRITTEN BY SUBSEQUENT SIMULATIONS*Libraries: * Profile Libraries :* Local Libraries :.LIB ./././pspice jinshzuhen-pspicefiles/pspice jinshzuhen.lib * From PSPICE NETLIST section of C:OrCADOrCAD_10.5toolsPSpicePSpice.ini file:.lib nom.lib *Analysis directives: .TRAN 0 4S 0 10u .PROBE V(alias(*) I(alias(*) W(alias(*) D(alias(*) NOISE(alias(*) .INC .SCHEMATIC1.net * INCLUDING SCHEMATIC1.net * source PSPICE JINSHZUHENR_R4 N05859 0 10kC_C2 N05859 N007180 1u V_V2 N06084 0 +PULSE 5v 10v 0 0 0 1ms 0C_C1 0 N05859 1u V_V3 0 N10500 +PULSE 5v 10v 0 0 0 1ms 0R_R5 N06006 N06191 Rbreak 8.7kX_U1 N05859 N06006 N06084 N10500 N06191 uA741R_R1 N06006 0 4kR_R3 N007180 N06191 10k* RESUMING DCSweep.cir *.END* 11/03/16 23:11:30 * PSpice 10.5.0 (Jan 2005) * ID# 0 * * Profile: SCHEMATIC1-DCSweep F:pspice jinshzuhen-pspicefilesschematic1dcsweep.sim * Diode MODEL PARAMETERS* X_U1.dx X_U1.dy IS 800.000000E-18 800.000000E-18 RS 1 1.000000E-03 CJO 10.000000E-12 * 11/03/16 23:11:30 * PSpice 10.5.0 (Jan 2005) * ID# 0 * * Profile: SCHEMATIC1-DCSweep F:pspice jinshzuhen-pspicefilesschematic1dcsweep.sim * BJT MODEL PARAMETERS* X_U1.qx NPN LEVEL 1 IS 800.000000E-18 BF 93.75 NF 1 BR 1 NR 1 ISS 0 RE 0 RC 0 CJE 0 VJE .75 CJC 0 VJC .75 MJC .33 XCJC 1 CJS 0 VJS .75 KF 0 AF 1 CN 2.42 D .87 * 11/03/16 23:11:30 * PSpice 10.5.0 (Jan 2005) * ID# 0 * * Profile: SCHEMATIC1-DCSweep F:pspice jinshzuhen-pspicefilesschematic1dcsweep.sim * Resistor MODEL PARAMETERS* Rbreak R 1 * 11/03/16 23:11:30 * PSpice 10.5.0 (Jan 2005) * ID# 0 * * Profile: SCHEMATIC1-DCSweep F:pspice jinshzuhen-pspicefilesschematic1dcsweep.sim * INITIAL TRANSIENT SOLUTION TEMPERATURE = 27.000 DEG C* NODE VOLTAGE NODE VOLTAGE NODE VOLTAGE NODE VOLTAGE(N05859)-797.3E-06 (N06006)-778.0E-06 (N06084) 5.0000 (N06191) -.0018 (N10500) -5.0000 (X_U1.6) 168.7E-09 (X_U1.7) -.0018 (X_U1.8) -.0018 (X_U1.9) 0.0000 (N007180) -.0018 (X_U1.10) -.6085 (X_U1.11) 4.9603 (X_U1.12) 4.9603 (X_U1.13) -.5946 (X_U1.14) -.5946 (X_U1.53) 4.0000 (X_U1.54) -4.0000 (X_U1.90)-114.7E-06 (X_U1.91) 40.0000 (X_U1.92) -40.0000 (X_U1.99) 0.0000 VOLTAGE SOURCE CURRENTS NAME CURRENT V_V2 -5.656E-04 V_V3 -5.658E-04 X_U1.vb 1.687E-12 X_U1.vc 4.003E-12 X_U1.ve 4.091E-12 X_U1.vlim -1.147E-07 X_U1.vlp -4.000E-11 X_U1.vln -4.000E-11 TOTAL POWER DISSIPATION 5.66E-03 WATTS JOB CONCLUDED* 11/03/16 23:11:30 * PSpice 10.5.0 (Jan 2005) * ID# 0 * * Profile: SCHEMATIC1-DCSweep F:pspice jinshzuhen-pspicefilesschematic1dcsweep.sim * JOB STATISTICS SUMMARY* Total job time (using Solver 1) = 181.36五 仿真波形：R1=5K时：T（w0）=(R1+R2) / 3R1=1 稳定震荡 图PSP-5（1）R1=4k时: T（w0）=(R1+R2) / 3R11.1671 逐渐建立起振 图PSP-5（2）图PSP-5（3）R1=4k R2=RES时：T（w0）=(R1+R2) / 3R11.058
