What are the disadvantages of emitter follower?
One disadvantage is a voltage offset between input and outpur equal to one base-emitter voltage drop. This offset must be accounted for or removed via a transformer or coupling capacitor. Read More »

Why emitter follower is stable?
The emitter follower, or Class C amplifier, is stable because offset does not depend too much on temperature, nor is there a bias circuit that affects gain. The emitter voltage is about 0.7V less (NPN) or more (PNP) than the base. So long a... Read More »

Because of the geometry of the common collector configuration, changes in base voltage appear at the emitter. Said another way, what happens at the base pretty much happens at the emitter, and the emitter can be said to "mirror" or "follow"...

Colector resistance in an emitter follower circuit serves to place a limit on how much current can be supplied by the transistor. Often, the resistor is sized so that a short circuit in the load does not cause the transistor to fail.

Common emitter is the only transistor configuration that has an 180 degree phase difference between input and output. Common base and common collector outputs are in phase with the input.
