Saturation voltage.

The saturation voltage is a peculiar spec which is not needed by MOSFETs. Bipolar junction transistors have worked for decades to get a Vsat down to 0.1 volt, but for a MOSFET it is 0.00000 volts. The npn has a base p material swamped with electrons from collector to emitter, shorting out any diode drop artifacts.With reference to the op-amp comparator circuit above, lets first assume that V IN is less than the DC voltage level at V REF, ( V IN < V REF ). As the non-inverting (positive) input of the comparator is less than the inverting (negative) input, the output will be LOW and at the negative supply voltage, -Vcc resulting in a negative saturation of the output. Note that, from figure 2 of the data sheet, this will typically produce a saturation voltage of ~0.15 volts. If you can live with a slightly higher output voltage you can provide slightly less base drive, and extrapolating from the data sheet (always dangerous) your worst-case output voltage with a 9 mA / 90 mA combination ought to be …Input Voltage Range VCM-0.1 V 2 Voltage Gain AV MAX9092/MAX9094 500 V/mV Output Saturation Voltage VSAT ISINK ≤ 1mA 25 mV Output Sink Current IOUT VOUT ≤ 1.5V 5 16 mA Supply Current IS MAX9092/MAX9093 (both comparators) 100 180 µA MAX9094/MAX9095 (all four comparators) 220 360 Output Leakage Current TA = +25°C …The base-emitter voltage required is high and is two times the single standard transistor. High power dissipation due to high saturation voltage. The overall leakage current is high because the leakage current of the first transistor is amplified by the next transistor. That’s why the three or more stages of Darlington is impossible.

• Saturation region. This is the region where the transistor will be biased for the maximum amount of base current to be used to achieve maximum current at the collector and minimum voltage drop at the collector-emitter and which in turn makes the depletion layer as tiny as possible hence the flow of maximum current through our transistor ...See full list on learn.sparkfun.com

A bipolar junction transistor ( BJT) is a type of transistor that uses both electrons and electron holes as charge carriers. In contrast, a unipolar transistor, such as a field-effect transistor (FET), uses only one kind of charge carrier.

Oct 31, 2015 · 1 Answer. Sorted by: 1. The saturation of drain current Ids occurs when Vgd=Vt (pinch-off condition of n-channel MOSFET). So the saturation drain-source voltage is Vds=Vsat. Since Vgd=Vgs-Vds you can find that Vsat=Vgs-Vt. Share. Thus the "saturation" voltage of a Darlington transistor is one V BE (about 0.65 V in silicon) higher than a single transistor saturation voltage, which is typically 0.1 - 0.2 V in silicon. For equal collector currents, this drawback translates to an increase in the dissipated power for the Darlington transistor over a single transistor.I would like to know why op-amps saturate below their supply voltage. For instance I have a circuit with an LM358-N amplifier IC that is powered at +5 [V] and connected to ground on the other rail. Theoretically the saturation should be 5 [V] but it saturates actually at 3.7 [V].For the LED to light up properly, I assumed a forward current of 70mA and a voltage drop of 1.3V. The datasheet of the PN2222A states that at 70mA collector current, the saturation voltage VCE V C E will be about 0.06V. So. R2 = 5V − 1.3V − 0.06V 0.07A = 52Ω R 2 = 5 V − 1.3 V − 0.06 V 0.07 A = 52 Ω. Lowest value of β β equals 10 ...the knee-point voltage (VKNEE in Fig. 3) is the voltage at the point where the tangent to the curve (on log-log axes) is at 45 degrees to the abscissa [3] [4]. The saturation voltage (VSAT) is graphically found by locating the intersection of the straight portions of the excitation curve on log-log axes [3]. Excitation Voltage (V) Fig. 3.

Second step is to determine the slope (1/S) of the upper part of the saturation curve, being careful that the curve is plotted on log-log scales with the decade spacing equal on both axes. “S” is defined as the reciprocal of this slope. You should get a slope such that S is in the neighborhood of 15 < S < 25. Schematic drawings of op amp circuits sometimes show the voltage supply rails, but not always. Op amp saturation. Voltage rails typically range between and volts, depending on the particular op amp selected. The output voltage of an op amp is not capable of exceeding the power supply voltage.

The threshold voltage for the IGBT is the minimum gate bias voltage required to observe on-state current flow. Typical IGBT products have a threshold voltage of 4 V with a gate drive voltage of 15 V used for on-state operation. The threshold voltage of these high-voltage devices is typically larger than for low-voltage (e ...The saturation voltage scales almost linearly with the gate voltage (V SAT ≈ V G –V T, where V T is the threshold voltage). For saturation to be strong, i.e. “flat” output characteristics above V SAT , the insulator thickness must be significantly smaller than the channel length (long channel rule), which imposes a design constraint.
