Bjt amplifier graph
Web\$\begingroup\$ "Therefore Re must always be smaller than RL for small signals and <= 1/2 RL for full negative swing when AC coupled". Surely that's not necessary. Even if RL is … WebIn order to analyze the operation of the BJT as an amplifier, an AC (or small signal) equivalent circuit is utilized. A widely used small signal circuit model is called the Hybrid-π model and is shown in Figure 6.7. Use of this small signal model assumes the BJT is operating in its normal active region; that is, it is biased at a Q point in the
