It’s a simple but ... Because the emitter is grounded, even if sometimes via a resistor, this transistor configuration is referred to as a Common Emitter amplifier. In this circuit if you ...

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 ...

Figure 1 A simple amplifier circuit suited for inductive sources such ... This rather high value is provided by the common emitter input stage (low noise transistor Q1) with dynamic load R3, Q2. While ...

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.
