Probably the most important characteristic of real world diodes that needs to be understood is the current-voltage relation. With a component like a resistor the current-voltage relationship is linear which is simple to understand. In a diode however, this relationship is non-linear! This is crit...
The current-voltage relation of each diode has been investigated within the approximation of Shockley's law of junctions. The width dependency of the currents for these diodes has also been modelled and it has been found that the current density of both the diodes decreases with de...
a capacitance Cd with the contributions from the junction capacitance Cj of the photodiode and the parasitic capacitance of packaging, a parallel resistance Rp representing the slope of the current/voltage relation near the bias point, and a series resistance Rs arises from the resistance of the ...
Zener diodes operate in the reverse breakdown region. By allowing them to conduct current in the reverse direction when a certain voltage is applied. In electronic circuits, Zener diodes act as voltage regulators. In order to maintain a stable voltage output despite changes in input voltage or lo...
The output power density of a TRD can be calculated by the detailed balance analysis of the current-density–voltage relation5,6. To determine the output power density, we assumed that the absorptivity for each of the three possible types of transitions (CB–VB, CB–IB and IB–VB) is cons...
Here's the LTspice simulation of a typical 5.1V, 500mW Zener for both a linear and a log horizonal-axis current scale: The log-scale, straight line at low currents shows a log relation between voltage and current. The linear-scale straight-line rise in voltage with current above about ...
Terminals 1 and 0 are biased by a DC current source, labeled I1 = I, and the voltage across the same terminals, V1 = V is measured. It is important to note that in our measurements terminal 2 is floating unless stated otherwise. In practice terminal 2 can be a ...
Zener diodes are operated in their reverse breakdown mode to provide voltage regulation. And notice voltage regulation in acircuit. And voltage regulation means it is keeping a voltage at a very stable value. The point where the reverse current begins to increase is called the knee voltage. And...
a The critical current on positive (blue line) and negative (red line) branches is plotted as a function of the magnetic field. The black curve represents the rectification effect. It is the mean value of the voltage measured as the bias current is set such that it exceeds the lower criti...
A DC circuit has a single battery of voltage V = 10.0 V attached to a resistor R = 100 Ohms. If the voltage is increased to 20.0 V, then by what factor does the power emitted by the resistor increase?An AC generator delivers an rms current of 3.30 A to a...
