[Paulo]’s calculator will therefore compute most of the characteristics of two class A common emitter/collector amplifiers for specified loads.

Can you do the same thing with electronic circuits? The answer–perhaps not surprisingly–is yes. Consider this simple common emitter amplifier (I modeled it in PartSim, if you’d like to open ...

Figure 2 This amplifier circuit produces the distorted waveform in Figure 3. Diode D 1 compensates for the distortion inherent in the npn transistor. The voltage gain of a common-emitter amplifier ...
