How do you find IDSS from the characteristics curves of a JFET?
To find the drain-source saturation current (IDSS) from the characteristics curves of a JFET, locate the transfer characteristic curve, which plots the drain current (ID) against the gate-source voltage (VGS). IDSS is identified as the maximum drain current occurring when VGS equals zero (VGS = 0V). This point corresponds to the intersection of the ID curve with the vertical axis (ID axis) on the graph. Reading the value at this point gives you the IDSS for the JFET.
Why self bias is not used in enhansement type MOSFET?
Because for creating channal we need voltage at gate if there is no voltage at ate then VGS=0 this mean no amplificatiion can be done.
What is saturation current for JFET?
The saturation current for a Junction Field-Effect Transistor (JFET) is the maximum drain current (Id) that can flow through the device when it is in saturation mode, meaning the gate-source voltage (Vgs) is sufficiently negative to fully pinch off the channel but not so negative as to turn the device off completely. This current is largely determined by the physical characteristics of the JFET, including the device's geometry and doping levels. The saturation current is typically denoted as Idss, which represents the drain-source current when the gate-source voltage is zero (Vgs = 0). This parameter is crucial for understanding the JFET's operation and its transfer characteristics.

What does the acronyms VGS stand for?
VGS could stand for many things. Some of the more popular are Videregaende Skole, which is a school in Norway, and Virtual Game Station or Video Game System. Another very common one is Voodoo Glow Skulls, which is a ska band.
Define the trans-conductance gm of a JFET?
gm = d(ID)/d(VGS), where ID = drain current, and VGS = gate bias, with all other biases fixed and all biases referenced to the source voltage. gm is the measure of how much the drain current changes with an incremental change of VGS. Practically, you measure (ID, VGS) pairs at a fixed VDS for a range of VGS. Then gm at a certain (VGS=VGS1) is simply (ID2-ID1)/(VGS2-VGS1), where 1,2 signify consecutive pairs of (ID, VGS). In other words, you can plot ID versus VGS on an x-y plot with VGS being the x-axis. Whichever way you measure the slope at a certain (VGS=VGS1) on the curve is the gm value. Please note that gm for an MOSFET is the same in definition. =============================
Are vgs jeans the same as vigosso?
Do you mean Vigoss? Yes, VGS are the version of Vigoss jeans once sold at J C Penney and are no longer available. You can find them on Ebay.

A N5459 has vgs=-8v and Idss=16mA.What is the drain current at the half cut off point?
▪ A 2N5668 has VGS(off) = -4 v and IDSS = 5mA. What are gate voltage and drain current at the half cutoff point? ▪ A 2N5459 has VGS(off) = -8 v and IDSS = 16mA. What is the drain current at the half cutoff point?
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 pinch off?
Pinch off voltage is defined as the gate-to-source voltage at which drain-to-source current is zero.Proof:-(In the saturation region)IDS = IDSS [1- (VGS/VP)]2When IDS = O ,VGS = VP
Does an N channel JFET require a positive or negative value for Vgs?
To create the depletion layer required for JFET operation the gate-source junction must be reverse biased.for N channel, the channel must be positive relative to the gate meaning Vgs must be negativefor P channel, the channel must be negative relative to the gate meaning Vgs must be positive
Does an n-channel JFET requires a positive or negative value for VGS?
To create the depletion layer required for JFET operation the gate-source junction must be reverse biased.for N channel, the channel must be positive relative to the gate meaning Vgs must be negativefor P channel, the channel must be negative relative to the gate meaning Vgs must be positive

In MOSFET the pinch-off voltage refers to?
This refers to the voltage Vds that counteracts the opening of the n-channel (NMOS), at the drain end. Since the width of the channel is a function of Vgs - Vtn, the mosfet saturates (pinches off) when Vds is greater or equal than/to Vgs - Vtn.
