PartSim is used in this example to simulate the Common Emitter Amplifier. The base bias voltage is set with the voltage divider arrangement. The input signal is amplified by the 2N2222 NPN transistor.
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 ...
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 to ...
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 sink’s ...
