What is the influence of gate voltage on drain source breakdown voltage in mos transistors?
Drain-to-source breakdown voltage (BVdss) should not change appreciably until the gate-to-source voltage (Vgs) approaches the device's threshold voltage (Vth). In that case, the drain to source voltage becomes the product of the drain-to-source current (Ids) and the device's on-state resistance (Rds-on) at the given Vgs.
What else can I help you with?
Why you need to connect resistor in series for the practical voltage source?
A resistor is connected in series with a practical voltage source in order to determine the current produced by the source.
Is a battery provides not a source of constant current or a source of constant voltage?
Batteries will provide a source of constant voltage. A battery also can be used to produce an electrical current immediately upon a necessary connection.
Why can't the potential barrier of a diode be used as a voltage source?
The potential barrier of a diode is caused by the movement of electrons to create holes. The electrons and holes create a potential barrier, but as this voltage will not supply current, it cannot be used as a voltage source.
What is the use of substrate in Field Effect Transistor?
The use of substrate in Field Effect Transistors is for it to serve as insulating material between the gate and the source.
How do you calibrate your VOM?
A: Three way must have a resistance and voltage source and current source to a very close tolerance,
How do you xxplain the zener shunt regulator?
zener diode is a special type of pn junction diode that work in breakdown region . There are two types of brekdowns in zener i.e avlanche breakdown and zener breakdown depending on the doping concentration. A zener diode in an on state can be considered as a voltage source ,equal to its zener voltage n hence act as an voltage regulator
Why you use current source in data transmission?
A: The main advantage for a current source transmission is low source impedance. extraneous voltage influence is reduced by that characteristic.
How Zener diode can be used as a reference voltage source?
Zener diodes only allow reverse-biased currents of above a certain (breakdown) voltage. You can use it to test if a current has a voltage above or below a specific number of volts.
How transistors are classified on the basis of power?
There are two primary types of transistors classified on the basis of power: bipolar junction transistors (BJT) and field effect transistors (FET). Bipolar junction transistors are current-controlled devices, meaning that the amount of current flowing through the device is controlled by the voltage applied to the base electrode. The base-emitter voltage (VBE) and base-collector voltage (VBC) determine the amount of current flowing through the device. The current flowing through the device is given by the following equation: I = β * (VBE - VBC) Where β is the current gain of the transistor. Field effect transistors are voltage-controlled devices, meaning that the voltage applied to the gate electrode controls the amount of current flowing through the device. The voltage applied to the gate electrode determines the width of the conducting channel between the source and drain electrodes. The current flowing through the device is given by the following equation: I = μ * W * (VGS - VDS) Where μ is the mobility of the carriers in the channel, W is the width of the conducting channel, VGS is the voltage applied to the gate electrode, and VDS is the voltage applied to the drain electrode.
What is source of voltage?
Energy is the source of voltage
What are the two transistor switches inside a CPU?
The two types of transistor switches inside a CPU are NMOS (n-channel metal-oxide-semiconductor) and PMOS (p-channel metal-oxide-semiconductor) transistors. NMOS transistors conduct when a positive voltage is applied to the gate, allowing current to flow from drain to source, while PMOS transistors conduct when a negative voltage is applied, allowing current to flow from source to drain. Together, these transistors form complementary pairs, enabling efficient logic operations and the construction of complex circuits such as gates and flip-flops within the CPU. This complementary technology is commonly referred to as CMOS (complementary metal-oxide-semiconductor).
Explain how a current flows in a semiconducting diode in the two states of biasing?
Let me answer as I've learned. In this case, if the voltage source for forward bias is greater than the voltage source for reverse bias, current will flow in this semiconductive diode. And another way may occur. That is, in case reverse bias voltage is as large as breakdown voltage, reverse breakdown current ,which is because of the minority carrier in p region, will flow and this current can be large to damage the diode. If there is any mistake in my answer, please correct me and I'll thank you for that.
What is breakdown mechanism in the semiconductor diode?
a conductor which doped interncily i.e doped externaly is semiconductor m=1/1-(v/vbd)n m=multipulfactors v=applied revese voltage vbd=break down reverse voltage n= emperical constant n=4 for n-type si n=2 forp-type si
What an led accepts whether ac or dc voltage?
A: A LED is a diode that emit photons when exited with enough current and/or voltage. it does not care where the source come from. for AC IT WILL WORK PROVIDED A SERIES DIODE IS ADDED that is there to prevent the led from burning up when the reverse voltage exceed the saturation current . these devices have a very low reverse voltage breakdown limitation and if they breakdown usually the power dissipation will be exceeded and blow up.
Explian action of zener diode as a regulator?
Zener predicatively will break down at a voltage as manufactured and sustain that voltage as long as the source can provide the current. The limitation is the zener power dissipation for each device. It Regulates by maintaining that breakdown voltage until its current is reduced or its break down voltage is reduced.
Is it possible to use source transformation to dependent voltage source?
Yes.Source transformation in dependent voltage source can be solved the same like independent voltage source
How will you differentiate the diodes whether it is Zener or avalanche when you are given two diodes of rating 6.2 v and 24V?
Oh, what a happy little question! To differentiate between Zener and avalanche diodes, you can look at their voltage ratings. A Zener diode typically has a lower voltage rating, like 6.2V, while an avalanche diode usually has a higher voltage rating, like 24V. Just remember, each diode has its own special purpose and they all bring joy to our electronic landscapes.
