PN Junction Diode Applications: An ideal PN Junction Diode Applications is a two terminal polarity sensitive device that has zero resistance (i.e., diode conducts) when it is forward biased and infinite resistance (i.e., diode does…
Switching Diode in Electronics: In discussing the rectifier diodes, the importance of reducing the reverse-bias current and the power losses under forward bias to the minimum was emphasized. But in case a junction diode is…
PN Diode Switching Times: A P-N junction diode may be used as an electrical switch. The electrical circuit can be made 'on' and 'off' by forward biasing or reverse biasing the diode. In both the…
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 combination of electric elements properly…
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 to very high reactance (XC…
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 in rectification (i.e., in conversion…
Series Diode Configurations with DC Inputs: The approximate models discussed in preceding section are used for investigation of a number of series diode configurations with dc inputs. This establishes a foundation in diode analysis that…
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 response of dependent variables to…
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 is forward biased, it will…
What is Diode Resistance? What is Diode Resistance? - As already discussed, a forward-biased diode conducts easily whereas a reverse-biased diode restrains the flow of current, so a diode has a low forward resistance as…
