common emitter amplifier - A BJT circuit in which the emitter connection is common to both input and output.
emitter feedback - Coupling from the emitter output to the base input of a bipolar junction transistor.
emitter follower - A common collector amplifier. Has a high current gain, high input impedance and low output impedance.
emitter - The semiconductor region from which charge carriers are injected into the base of a bipolar junction transistor.

Uni-junction
Unijunction Transistor The unijunction transistor (UJT) works like a switch. It doesn't amplify the voltage, it just lets current through or not depending on the in input voltage. Irrespective


Bipolar Transistors
Bipolar Transistors One of the two types of transistors are bipolar transistors. From Diodes we learnt about PN junctions. Now with bipolar transistors we add another layer to make it PNP or NPN depe
