Next step electronics 3; A simple BJT transistor bias circuit

The first step in every transistor based amplifier design is to define its bias circuitry. Perhaps the most important parameter in the schematic is the DC current in the collector of the transistor, because it is directly proportional to its small-signal gain. In this post a simple bias method for bipolar junction transistors (BJT) is being shown, where the collector current is being set with relative accuracy.
