一、运算器的基本方程如图一所示,设直流放大器的增益为(-A)结点电流为 ig,等效漂移输入电压为e_2,则11=ig=if(e_i-e_g)/(Z_i)-i_g=(e_g-e_o)/Z_fe_o=-A(e_g+e_
First, the basic equations of the operator as shown in Figure 1, set the gain of the DC amplifier (-A) node current ig, equivalent drift input voltage e_2, then 11 = ig = if (e_i-e_g) / ( Z_i) -i_g = (e_g-e_o) / Z_fe_o = -A (e_g + e_
