Question

Quizplus · Accepted Answer

In most practical BJT (Bipolar Junction Transistor) buffers, driving the transistor into cutoff means the base-emitter junction is not forward-biased, which typically occurs when the input voltage (Vin) is approximately equal to the emitter voltage (VEE). This condition ensures that the base-emitter voltage is not sufficient to turn the transistor on.
