Transistor Biasing and Thermal Stabilization topics include: Operating point, bias stability, collector-to-base and collector-emitter bias, self bias, bias compensation, thermistor, thermal runway and stability. Transistor biasing is the process of setting a transistor's DC operating voltage or current conditions to the correct level. It's necessary to activate a transistor and make analog and digital operation possible.  The process of making the operating point independent of temperature changes or variations in transistor parameters is known as stabilization.
