Semiconductor Converter Controlled Drives: These are now widely used both in ac and dc tractions involving dc and ac motors, and the conventional drives have all become outdated, and will…
Semiconductor Microwave Devices Articles: Trapatt Diode Construction and Working: The Trapatt Diode Construction and Working is derived from and closely related to the IMPATT diode. Indeed, as pointed out near…
Semiconductor Lasers: Semiconductor Lasers was discovered in 1962 that a gallium arsenide diode, such as the one shown in Figure 12-41, is capable of producing laser action. This occurs when…
Schottky Barrier Diode: Schottky junctions have been shown and described throughout this chapter, in conjunction with various devices that use them in their construction in Figure 12-4. Accordingly it will…
Pin Diode Construction: The Pin Diode Construction consists of a narrow layer of p-type semiconductor separated from an equally narrow layer of n-type material by a somewhat thicker region of…
Tunnel Diode Equivalent Circuit: The Tunnel Diode Equivalent Circuit, when biased in the negative-resistance region, is shown in Figure 12-18. At all except the highest frequencies, the series resistance and…
Varactor Diode Operation and Characteristics: Varactor Diode Operation and Characteristics were first used in the early 1950s as simple voltage-variable capacitance and later for frequency modulation of oscillators. They thus…
Trapatt Diode Construction and Working: The Trapatt Diode Construction and Working is derived from and closely related to the IMPATT diode. Indeed, as pointed out near the beginning of this…
