The value of the small protective input base resistor is not critical. (a) Observe the follower operation. Drive it with a symmetrical sine wave at the input (check that the signal from the waveform generator has no dc offset voltage).
WebJan 11, 2010 · Emitter Follower Voltage Regulator. With our previous voltage regulator with the zener diode, we had the problems of the zener diode wasting power and needing a high power diode if there was a lot of current going through the diode. If we add an emitter-follower, we can use a much smaller diode and less current to achieve the same effect. WebThe breadboard connections are shown in figure 1. The output of the channel A voltage generator, CA- V, is connected to the base terminal of Q 1. The collector terminal is connected to the positive (+5 V) supply. The emitter terminal is connected to both the 2.2 KΩ load resistor and the channel B scope input CB-H.
