Saturation voltage
Electronically, saturation is defined as the point where an amplifier cannot amplify any more, it has run out of operating range. The transistor Q1 is amplifying the current from Q2, drawing load current in the inductor and pulling the voltage down; the voltage can't pull any further than saturation. (Conversely, when Q2 turns off, Q1 also ...Find the values required for W and R in order to establish a drain current of 0.1 mA and a voltage VD of 2 V. - Solution. VD =VG. VSD >VSG. VT saturation.

Collector−Emitter Saturation Voltage (IC = 500 mA, IB = 50 mA) VCE(sat) − − 0.7 VdcIn this case, the saturation voltage of a low side NPN transistor isn't a big deal. With only 1.2 mA collector current, you can easily run it well into saturation. 200 mV is a typical value of saturation voltage in a case like that. Even if it is as high as 500 mV, you can easily design for that just be lowering the resistor values.Saturation is employed to limit current in saturable-core transformers, used in arc welding, and ferroresonant transformers which serve as voltage regulators. When the primary current exceeds a certain value, the core is pushed into its saturation region, limiting further increases in secondary current.In saturation, the base-collector junction is forward biased and the relationship between the base and the collector current is not linear. Therefore the collector current at saturation is () ()CC CE C C VVsat Isat R − = (1.9) In saturation the collector-emitter voltage, , is less than the . Typically, the at saturation is about 0.2 Volts ...According to wikipedia, the MOSFET is in saturation when V (GS) > V (TH) and V (DS) > V (GS) - V (TH). That is correct. If I slowly increase the gate voltage starting from 0, the MOSFET remains off. The LED starts conducting a small amount of current when the gate voltage is around 2.5V or so.The required base current for good saturation is typically 1/10th or 1/20th of the collector current (forced Beta of 10 or 20), as shown in the data sheet where it gives the Vce(sat) voltage. That is the base current value you should use.VCE Figure 1.

Look at the excitation graph (not shown) the excitation current Ie for 10.7V of secondary excitation voltage is approximately 0.22A. Total primary current= (60A+20*0.22A) =64.4A. IGBT combines the low saturation voltage of a transistor with the high input impedance and switching speed of a MOSFET. The outcome obtained from this combination delivers the output switching and conduction characteristics of a bipolar transistor, but the voltage is controlled like a MOSFET.A saturation function can be symmetrical (one example is the output voltage of an operational amplifier) or asymmetric. The waterbath is a good example for an asymmetrical saturation function: the heater power has an upper limit dictated by the heating element and the driver power, but the element can only heat.We would like to show you a description here but the site won’t allow us.low-saturation-voltage capability of bipolar transistors as illustrated in Figure 1, and they are the right choice for high-current and high voltage applications. IGBT and MOSFET operation is very similar. A positive voltage, applied from the emitter to gate terminals, produces a flow of electrons toward the gate terminal in the body region. IfAug 12, 2016 · The input voltage of 1V (at first, without taking the feedback path into consideration) will appear at the non-inv. opamp node and will bring the output immediately into saturation (pos, supply voltage Vcc). Now - we have two voltage sources at both ends of the resistor chain: At the left Vin and at the right Vout. 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.LM393, LM393E, LM293, LM2903, LM2903E, LM2903V, NCV2903 www.onsemi.com 3 MAXIMUM RATINGS Rating Symbol Value Unit Power Supply Voltage VCC +36 or ±18 V Input Differential Voltage VIDR 36 V Input Common Mode Voltage Range VICR −0.3 to +36 V Output Voltage VO 36 V Output Short Circuit−to−GroundThe base-emitter voltage is almost two times compared to a normal transistor.
