WebThe bipolar junction transistor (BJT), which will be studied in Chapter 6, is a three-terminal device that when powered-up by a dc source (battery) and operated with small signals can be modeled by the lin- ear circuit shown in Fig. 1.19(a). ... The heart of the model is a transconductance amplifier represented by an input resistance between B ... WebJul 25, 2024 · Find the small signal input resistance to a BJT amplifier. Relevant Equations: iB = Vtest / Rinput iC = beta x iB The diagram of the BJT amplifier small signal model is below. This is not really a homework question as I am self-learning electronics, but I was advised it may be better placed here than in the technical portion of the forum. railway designation list
