The saturation current (or scale current), more accurately the reverse saturation current, is the part of the reverse current in a semiconductor diode caused by diffusion of minority carriers from the neutral regions to the depletion region. This current is almost independent of the reverse voltage.
Velocity saturation greatly affects the voltage transfer characteristics of a field-effect transistor, which is the basic device used in most integrated circuits. If a semiconductor device enters velocity saturation, an increase in voltage applied to the device will not cause a linear increase in current as would be expected by Ohm's law ...
Varying the current in the control winding moves the operating point up and down on the saturation curve, controlling the alternating current through the inductor. These are used in variable fluorescent light ballasts, and power control systems. [11] Saturation is also exploited in fluxgate magnetometers and fluxgate compasses.
Saturation (magnetic), the state when a magnetic material is fully magnetized; Saturated fluid or saturated vapor, contains as much thermal energy as it can without boiling or condensing Saturated steam; Dew point, which is a temperature that occurs when atmospheric relative humidity reaches 100% and the air is saturated with moisture
The effect of reverse saturation current on the I-V curve of a crystalline silicon solar cell are shown in the figure to the right. Physically, reverse saturation current is a measure of the "leakage" of carriers across the p–n junction in reverse bias.
When no additional photoelectrons can be collected, the photoelectric current attains a saturation value. This current can only increase with the increase of the intensity of light. [citation needed] An increasing negative voltage prevents all but the highest-energy electrons from reaching the collector.
Gold prices and the U.S. dollar typically have an inverse relationship, but that's been changing. Here's what to know now.
The theory is similar to that of a single probe, except that the current is limited to the ion saturation current for both positive and negative voltages. In particular, if V b i a s {\displaystyle V_{bias}} is the voltage applied between two identical electrodes, the current is given by;
