Questions & Step-by-Step Solutions
In a BJT, what does the term 'active region' refer to?
Step 1: Understand what a BJT is. A BJT (Bipolar Junction Transistor) is a type of transistor used to amplify or switch electronic signals.
Step 2: Learn about the three regions of operation for a BJT: cutoff, active, and saturation.
Step 3: Identify the active region. The active region is the part of the BJT's operation where it can amplify signals.
Step 4: Know the boundaries of the active region. It operates between two points: cutoff (where the transistor is off) and saturation (where the transistor is fully on).
Step 5: Remember that in the active region, the BJT can control a large output current with a small input current, which is essential for amplification.
