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…
Gunn Diode Working Principle: A practical Gunn Diode Working Principle consists of a slice like the one shown in Figure 12-24, sometimes with a buffer layer between the active layer…
Parametric Amplifier Types: The basic Parametric Amplifier Types have already been discussed in detail, but several others also exist. They differ from one another in the variable reactance used, the…
Measurement of High Direct Current: High magnitude direct currents are measured using a resistive shunt of low ohmic value. The voltage drop across the resistance is measured with a millivoltmeter.…
Series Impedance Voltmeter: For power frequency a.c. measurements the Series Impedance Voltmeter may be a pure resistance or a reactance. Since resistances involve power losses, often a capacitor is preferred…
