Broadband practical amplifier consisting of two stages of common emitter amplifier
Shown is a practical broadband amplifier consisting 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 .
