Electronics 1. Explain the construct ion of transistor( BJT) The thin and lightly doped central region is known as the base (B) and has majority charge carriers of opposite polarity to those in the surrounding material. The two outer regions are known as the emitter (E ) and the collector (C ). Under the proper operating conditions the emitter will emit or inject majority charge carriers into the base region, and because the base is very thin, most will ultimately reach the collector. The emitter is highly doped to reduce resistance. The collector is lightly doped to reduce the junction capacitance of the collector-base junction. 2. Draw the symbol of PNP , NPN transistor . Fig :NPN bipolar transistor and b) PNP bipolar transistor 3. Draw the Characteristic curves of an NPN transisto r . Fig: Characteristic curves of an NPN transistor.
