Emitter follower low-frequency gain, input impedance, and output impedance. The emitter follower ( Figure 5.11 (a)) is a buffer stage with high input impedance, low output impedance, and a gain of approximately unity. Using the small-signal low-frequency circuit of Figure 5.11 (b), we will find the gain, input resistance seen at the base, and ...

SIMPLE EMITTER-FOLLOWERS. THE SIMPLE EMITTER-FOLLOWER. The simplest discrete circuit-block is the emitter-follower. It acts as a unity-voltage-gain buffer. A buffer is a stage with high input impedance and low output impedance; typically it prevents things downstream from loading things upstream. The simple emitter-follower does not have a

Emitter follower input resistance DC coupled emitter follower, common collector circuit. The simplest way of connecting an emitter follower is to directly couple the input as shown below. Often the collector of the previous stage will be at approximately the mid rail voltage, and this means that it can be directly coupled to the buffer stage.
