    Single stage CE amplifier, Lecture-XXI and XXII.

    In the discussions of the BJT so far we have discussed, their construction and working. It has been mentioned earlier that the BJT is capable of 2 functions, namely switching and amplification. It works under 3 regions of operations: active region which lies between the reverse-reverse biased cutoff region and forward-forward biased saturation region. In…

    Bipolar Junction Transistors (BJT), Lecture-XV and XVI.

    Today we will discuss another line of application of the pn semiconductor diodes: the so called bipolar junction transistors or BJT in short. There are two ways in which pn junction diodes can be joined together sharing a common P or N terminal. This produces 3 layer, 2 junction, 3 terminal devices. Such devices are…
