我們可以將左下圖的CE放大器小信號等效電路(無信號源及負載),視為右下圖的放大器等效電路(Amplifier equivalent circuit),其中Rin 稱為放大器的輸入電阻(Input resistance),Avo為開路增益(Open-loop gain,即輸出端不接任何負載時的增益),Ro為輸出電阻(Output resistance)。 由電路的等效關係得知Rin、Avo及Ro : ...

2) I have read in a few places that this kind of arrangement needs some kind of negative feedback - I have none but even so the circuit works just fine as an amplifier, with an unloaded voltage gain of about 34.
