### CONTROL OF THE POWER BIPOLAR JUNCTION TRANSISTORS What is Operating Point in Transistor? Q point Explanation. Given a specific type of transistor, biasing should result in the same or nearly the same bias point in every transistor of that type . . . this is called bias stability . Bias stability can also mean stability with temperature, with aging, etc., Finding a circuit's dc operating points is an essential step in its design and involves solving systems of nonlinear algebraic equations.
