Equivalent Circuit of a Diode: It is usually advantageous to replace a device or system by its equivalent circuit. An equivalent circuit of a device or a system is a…

Transition and Diffusion Capacitance: Transition and Diffusion Capacitance - Electronic devices are inherently sensitive to very high frequencies. Most shunt capacitive effects that can be ignored at lower frequencies due…

Diode as a Circuit Element: Diode as a Circuit Element - The P-N junction diode is considered as a circuit element. One of the most important application of diode is…

Up Down Circuit Analysis: Any circuit has independent variables (such as source voltages and branch resistances) and dependent variables (such as voltage drop across resistors, current and power). Determination of…

What is Real Diode? As already mentioned, an actual diode neither behaves as a perfect conductor when forward biased nor as a perfect insulator when reverse biased. When a diode…

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…

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…

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…
