Dec 19, 2008RFSim99 works with S-parameters. This means that not only will it simulate and analyse circuits built out of its internal library of components, but that it can accommodate any circuit block or stage for which these are known.

Single Transistor Audio Amp - Hackster
For improved speaker output a single transistor audio amp will be a great improvement. So what are our options? The maximum output to a 8Ω speaker can be calculated using the Ohms Law formula P = V * I, or in this case P = 5v * 300ma = 1. It is desirable for Vout to be 1/2 of V+ to drive the transistor in the middle of its operating range.
