The intrinsic layer of the PIN diode is a layer without doping, and as a result this increases the size of the depletion region - the region between the P and N layers where there are no majority carriers. This change in the structure gives the PIN diode its unique properties.
Be aware of possible complications. By weakening your immune system, HIV can leave you vulnerable to certain cancers and infections. These infections are called opportunistic because they take the opportunity to attack you when your immune system is weak.
Advanced Symptoms of HIV/AIDS. As HIV progresses, there may be bouts of diarrhea, nausea, vomiting, and weight loss. Other symptoms include severe headache, joint pain, and muscle aches. Shortness of breath, chronic cough, and difficulty swallowing are not uncommon. In the later stages, HIV can lead to short-term memory loss, mental confusion, and coma. The most advanced stage of HIV is called acquired immune deficiency syndrome (AIDS). At this stage, the immune system is severely compromised and infections become increasingly difficult to fight off.
