Bipolar Junction Transistor (BJT) – Formulas and Equations

http://faculty.cord.edu/luther/physics225/Handouts/transistors_handout.pdf WebBasic BJT Operation in Forward Active Consider and NPN BJT. Forward active is the standard mode of operation for BJT’s when they are used in analog electronics applications (amplifiers, etc.). Collector Current: Under forward active operation, the Emitter-Base junction is forward biased and the Base-Collector junction is reverse biased.
