49、定性。式中的负号表示uo与 ui反相。图中的 R2是一静态平衡电阻，即在静态时（输入信号ui0）,两个输入端对地的等效电阻要相等，达到平衡状态。其作用是消除静态基极电流对输出电压的影响。因此：R2R1/RF。从反馈类型来看，反馈电路自输出端引出而接到反相输入端。设ui为正，则 uo为负，此时反相输入端的电位高于输出端的电位，输入电流i1和反馈电流 if的实际方向即如图中所示，差值电流idi1if，即 if削弱了净输入电流(差值电流)，故为负反馈。反馈电流if取自输出电压 uo，并与之成正比，故为电压反馈。反馈信号在输入端是以电流的形式出现的，它与输入信号并联，故为并联反馈。因此，反相比例运算电

50、路是一个并联电压负反馈电路。另外，电路的输入电阻不高，输出电阻很低。4.2 同相比例运算电路输入信号从同相输入端引入的运算，便是同相运算。根据运算放大器工作在线性区时的分析依据：虚短路和虚开路原则u-=u+uii1if可得：文档编码:CF1F1H4M1W10 HT1L9X2H7G9 ZL3O6W4B3O1文档编码:CF1F1H4M1W10 HT1L9X2H7G9 ZL3O6W4B3O1文档编码:CF1F1H4M1W10 HT1L9X2H7G9 ZL3O6W4B3O1文档编码:CF1F1H4M1W10 HT1L9X2H7G9 ZL3O6W4B3O1文档编码:CF1F1H4M1W10 HT1L9X
