Bipolar Transistor Tutorial, The BJT Transistor
An automotive analogy for transistor operation is as follows: cutoff is the condition of no motive force generated by the mechanical parts of the car to make it move. In cutoff mode, the brake is engaged (zero base current), preventing motion (collector current). Active mode is the automobile cruising at a constant, … See more When a transistor is in the fully-off state (like an open switch), it is said to be cutoff. Conversely, when it is fully conductive between emitter and collector (passing as much current through the collector as the collector power … See more Lets set up a circuit for SPICE simulation to demonstrate what happens when a transistor is in its active mode of operation. (Figure below) In the … See more Each curve on the graph reflects the collector current of the transistor, plotted over a range of collector-to-emitter voltages, for a given … See more Often it is useful to superimpose several collector current/voltage graphs for different base currents on the same graph as in Figure below.
