WebThe role of an output stage is to provide power gain. It should have high input impedance and low output impedance. An obvious choice for this stage is the emitter follower. However, in order to provide both current sourcing and sinking capabilities, two complementary followers are needed, an NPN type to source current and a PNP type to … WebOct 26, 2016 · Objective. To design, build, and test an emitter-follower amplifier using a 2N3904 NPN transistor, with an input resistance of at least 1 KΩ that is capable of driving an AC-coupled 47 Ω load with a 1 VP-P sine wave. To increase the load to 10 Ω and observe that this heavier load can still be driven, limited by the available current.
