Broadband practical amplifier consisting of two stages of common emitter amplifier
As shown in the figure is a wide-band practical amplifier composed of a two-stage common emitter amplifier. Input, output and inter-electrode coupling all use capacitance. C4 and cs are emitter decoupling capacitors to eliminate AC negative feedback and enhance the ability of AC signal amplification. The inductor (10 yH) connected to the -15V power supply and It6, C3, Rii, Island, C2, etc. are all filters used to filter out ripples in the power supply.
