Determination of Diode Characteristics: Determination of Diode Characteristics - The forward characteristics of a diode can be obtained by use of the circuit depicted in Fig. 7.16 (a). The diode voltage is set at a…
Terminal Characteristics of Junction Diodes: The volt-ampere characteristic of a silicon junction diode is depicted in Fig. 7.14. The same Terminal Characteristics of Junction Diodes is depicted in Fig. 7.15 with some scales expanded and…
Quantitative Theory of PN Junction Diode: Quantitative Theory of PN Junction Diode - Here an expression for the total current will be derived as a function of the applied voltage with the assumption that depletion…
Current Components in PN Junction Diode: A Current Components in PN Junction Diode with a forward bias with an external voltage V is shown in Fig. 7.12 (a). Due to forward bias, there exists a…
What is an Ideal Diode - Working and its V-I Characteristics: Diode is a two terminal device that permits only unidirectional conduction. It conducts well in the forward direction and poorly in the reverse direction.…
Breakdown Voltage of PN Junction Diode: When an ordinary P-N junction diode is reverse biased, normally only very small reverse saturation current flows. This current is due to movement of minority carriers. It is almost…
Diode Failure Modes and Causes: We would certainly like for solid-state components to be 100% reliable but this is unfortunately not true. All solid-state devices have a certain probability of failure. To be good circuit…
Explain Steady State Conditions in Semiconductor: Explain Steady State Conditions in Semiconductor - When the P-N junction is forward biased, current flows quite freely P to N in a P-N junction, as discussed in Fig.…
Metal Semiconductor Junctions: Metal semiconductor junctions are very common in all semiconductor devices and are very important. Depending upon the doping concentration, materials, and the characteristics of the interface, the metal semiconductor junctions can act…
Zero bias PN junction: Zero bias PN junction - Here we will examine the properties of the step junction in thermal equilibrium, where no currents exist and no external excitation is applied. We will determine…
