我們通過(guò)選擇合適的電路元件參數(shù)，使其發(fā)射結(jié)正偏、集電結(jié)反偏（Uc＞Ub＞0），那么該電路就工作在放大狀態(tài)，輸入、輸出電流滿足ic=βib關(guān)系，也即集電極電流是基極電流的β倍。設(shè)輸入為一正弦交流小信號(hào)u1（注意是小信號(hào)，也即在±0.7v內(nèi)，如果超過(guò)了這個(gè)范圍會(huì)出現(xiàn)飽和失真、截止失真問(wèn)題），其大小和方向均做周期性變化，平均值為零；經(jīng)過(guò)電容C1的耦合后其與原直流偏置電壓Ube疊加后變成了脈動(dòng)直流信號(hào)u2，也即u2的波形和u1一樣，但u2均為正值即u2＞0，u2的平均電壓不在為零，這樣做的目的是因?yàn)榘l(fā)射結(jié)導(dǎo)通有一個(gè)死區(qū)電壓，抬升電壓后才能完整的信號(hào)輸入，否則信號(hào)會(huì)被削去大部分，造成了嚴(yán)重的失真。
