WebThe term bipolar refers to the use of both holes and electrons as current carriers in the transistor structure. Figure 1: Basic BJT structure. The pn junction joining the base region and the emitter region is called the base-emitter junction. The pn junction joining the base region and the collector region is called the base-collector junction. WebThe circuit which provides transistor biasing is called as Biasing Circuit. Need for DC biasing If a signal of very small voltage is given to the input of BJT, it cannot be amplified. Because, for a BJT, to amplify a signal, two conditions have to be met. The input voltage should exceed cut-in voltage for the transistor to be ON.
