An ideal voltage amplifier with a voltage gain of -1000 has a 0.1pF capacitance connected between its output and input terminals. If the amplifier is fed from a voltage source Vsig having a resistance Rsig, find the transfer function as a function of the complex-frequency variable s.(Do not use Miller theorem.) 原本用密勒的話,轉移函數沒有零點;不能用密勒的話,轉移函數會多一個零點嗎 ? 又轉移函數該怎麼求呢 ? -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 111.249.166.93
harrypotter2:(-Vo/1000)*(SC+1/Rsig)=(Vsig/Rsig)+VoSC 12/30 20:36
harrypotter2:零點在無限大,分析:W→無限大,則Vo=-Vo/1000→Vo=0V 12/30 20:38
harrypotter2:第一行就是KCL用電導算 12/30 20:52
