摘要
本文通过对比单管放大器三种组态的交流等效电路与实际电路 ,分析了共射、共集和共基电路中 各交流分量与实际电流间的关系 ,揭示了交流等效电路的实质 。
Contrasting the amplifier′s alternating equivalent circuits with its real circuits, this article analyses the relation between the alternating components and the real current in common emitter amplifying circuit,common base and common collector, having exposed the reality of a alternating equivalent circuit and removed the perplexed when learning the three amplifier circuits.
