Detailed Solution
Download Solution PDFThe correct statement regarding the doping levels of the emitter, base, and collector regions in a bipolar junction transistor (BJT) is: The emitter is heavily doped, the base is lightly doped, and the collector is moderately doped.
- This doping profile is typical for an NPN (negative-positive-negative) BJT.
- The heavily doped emitter facilitates efficient injection of majority carriers into the base, while the lightly doped base allows for the transit of minority carriers across the base region.
- The moderately doped collector helps in the collection of majority carriers that have crossed the base.
- This specific doping arrangement is essential for the proper operation of the transistor in amplification and switching applications.
