The common emitter amplifier and emitter follower will be demonstrated using the same amplifier circuit. The main difference between the two will be where the output is taken.

Figure 1 The addition of a simple diode in the emitter circuit yields the symmetric waveform in Figure 4. Figure 2 This amplifier circuit produces the distorted waveform in Figure 3. Diode D 1 ...

The circuit in Figure 1 sinks a constant current (ICE3) through Q3’s collector and emitter. This design is balanced so changes in Q3’s base-emitter voltage (VBE) don’t affect the current ...

Last time on Circuit VR, we looked at creating a very simple common emitter amplifier, but we didn’t talk about how to select the capacitor values, or much about why we wanted them. We are going ...
