Bipolar Transistor Biasing

Figure 1
This NPN bipolar junction transistor is wired in the common-emitter configuration, meaning its emitter is grounded. Two basic equations dictate its behavior.

Going back to the basics is never a bad idea. Many electronics engineers are fluent with complex systems—such as microcontrollers, embedded OSes, or FPGAs—but seem to have more difficulties with single transistors. What a shame! A transistor can be a … Continue reading
