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 »

Answers to Other Common Questions
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...

A darlington emitter follower is two transistors operating as one. Both collectors are tied together. The emitter of the first is connected to the base of the second. The darlington exhibits very high gain. If hFe, for instance, on each tra...

The (Class C, Common Collector) Emitter Follower is used to amplify the available current from a voltage driving circuit that might be disturbed by the load impedance. If the actual voltage value is important, the emitter follower is often ...
