Saturation mode is when the drain voltage is higher than the gate voltage, at which point the channel becomes very wide and there's a good amount of current flow. This is also called the active mode. In comparison to the linear mode, where the current increases linearly vs drain to source voltage, in the saturation mode increasing the drain voltage further won't affect the current flow, since it's already saturated. Please note that it's assumed that the gate voltage is larger than the threshold voltage, which will turn on the FET.

Construction of mosfet in depletion region?
To make a depletion MOSFET, the channel must be doped with carriers; this is in total opposite to an enhancement MOSFET which avoids carriers in the channel at all cost. (because the carriers in the channel become the subthreshold leakage current) Since you need to pinch the channel against the substrate to guarantee to turn off the channel completely, there must be a reverse bias between the substrate and the source terminal. As a result, the source terminal of an N type depletion MOSFET must be tied to Vdd. This is also a complete opposite to enhancement MOSFET. In order to turn off the channel quickly, the carriers in the channel of depletion MOSFET are usually planted shallowly. This is a drastically different from enhancement MOSFET that carriers must be planted deeply into source terminal in order to support a large diffuse current. The construction of depletion MOSFET thus requires far less diffusion time than enhancement MOSFET.
Do equal changes in Vgs cause equal changes of Id?
No, equal changes in Vgs do not necessarily cause equal changes in Id for a MOSFET. The relationship between Vgs and Id is nonlinear and depends on the characteristics of the specific MOSFET being used, such as threshold voltage and transconductance. The current-voltage relationship in a MOSFET is governed by its operating region (ohmic, saturation, or cutoff).
What is saturation region in general?
Saturation region is one in which the output current is independent of the input and remains almost constant. Hence, MOSFETs in saturation are modeled as current sources( whose current is independent of voltage across it)
What are the advantages oF MOSFET inverter?
cause MOSFET are mainly the comes into category of Semiconductors, main work of inverter is to switch the contacts within microseconds, here i want to give some constructional things so it could go easy to understand the things, 1] MOSFET has a three satates, i]Deplition ii]enhancement iii]pick When the current go through the system the work of 'mft' has start as a implementing the depletion region(increasing the electrons in emitter collector junction) as and as the supply gets interrupted the MOSFET comes into work within our thinking due to high electrons consumption it goes extream fast switch the signal from one state to anther, actually MOSFET needs cery deep explination to understand it. but the main purpose is to stop reverse impulses and quike switching from one state to another.
Difference between de mosfet and e mosfet?
The basic difference is between JFET and enhanced MOSFET,although the construction of JFET and depletion MOSFET is different but their most of the characteridtics are same,i.e shockly equation can be applied on both of them,but in JFET we cant give to gate voltage, the +ve value,because it does not works, but in depletion we can give,but some limited +ve value. Now enhanced MOSFET is different,shockly equation cant be applied.The transfer characteristics are purely in +ve Vg region. i.e for E-MOSFET Vg should be > 0,for its proper function.
Why transistors are designed?
For switching applications transistor is biased to operate in the saturation or cutoff region. Transistor in cutoff region will act as an open switching whereas in saturation will act as a closed switch.
Which regions FET can be operated as a switch?
Saturation region(on) and Cut off region(off).
What arer the 3 legs of a transistor?
Emitter, Collector and Base cutoff region, saturation region, and liner region
Which regions in output characteristics are used to switching action of transistor in CE configuration?
In a common emitter (CE) configuration, the output characteristics used for switching action are primarily the active region and the saturation region. When the transistor is in the active region, it can amplify signals, while in the saturation region, it acts as a closed switch, allowing maximum current to flow. The transition between these two regions is crucial for effective switching, where the transistor is turned on (saturation) or off (cut-off) to control the output.
What is saturation and active region in a transistor?
The output current of a transistor is controlled by the current in the 'base' input: Increasing the control current will increase the output current in a more or less linear fashion. In the saturation region, this is no longer true: The transistor is nearing the limits of how much current it can conduct, so increasing the control current further has little or no effect. When using a transistor as an amplifier, you want to stay away from the saturation region as it would distort the signal you are amplifying. When using a transistor as an on/off switch, as in digital circuits, being in the saturated region is 'on' and a normal mode of operation.
What is the average cost of male enhancement surgery?
The average cost of male enhancement surgery varies depending on the region where the operation is performed. The average price overall is around 4-6k USD.
What is the zone of saturation and where is it?
Region where rock spaces are filled with water:it is below the zone of aeration and the water table
