Up Down Circuit Analysis

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 variation in independent variable is known as circuit Up Down Circuit Analysis. Consider a circuit given in Fig. 7.24. A …

What is Real Diode?

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 not conduct till the potential barrier V0 (0.7 V for Si and 0.3 V for Ge) at the junction is …

What is Diode Resistance?

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 compared to high blocking or reverse resistance. Forward Resistance. The resistance offered by a diode in the circuit, when forward …

Effect of temperature on PN diode characteristics

Effect of temperature on PN diode characteristics: Temperature on PN diode characteristics is very important consideration in the analysis or design of electronic devices or systems. It affects virtually all of the characteristics of a semiconductor device. The diode current at a given voltage depends upon the operating temperature. The variation may be determined from …
