1 The issue or topic may be set forth as a topical question, a hypothetical incident, a student experience, an actual case, etc. 2  Select panelists who are well informed about and have specific points of view regarding the issue or topic. 3  A panel discussion that includes three to five panelists is usually most workable.
A: Typically, they are constructed with PIN diodes. A PIN diode is simply a p-n junction diode that is designed to. have a very small junction capacitance (0.01 to 0.1 pf). A Sort of the opposite of the varactor diode! To see why this is important, recall diode small signal analysis. from your first electronics course.
a semiconductor device containing one p-n junction, used in circuits for converting alternating current to direct current More formal name semiconductor diode 2. the earliest and simplest type of electronic valve having two electrodes, an anode and a cathode, between which a current can flow only in one direction. It was formerly widely used as a rectifier and detector but has now been replaced in most electrical circuits by the more efficient and reliable semiconductor diode
