You’re going to build two simple transistor circuits, each using a single transistor. These circuits will allow you to observe the operation of a transistor as an amplifier, just as Walter ...

implementing as it does a complete simple op-amp with five transistors. Looking at the circuit diagram it follows the classic op-amp with a long-tailed pair of NPN transistors driving a PNP gain ...

Consider this simple common emitter amplifier (I ... For a normal silicon transistor, this should be about 0.6 or 0.7 volts, dependant on temperature. If the real circuit or an accurate simulation ...
