In this video, the transfer characteristics of the JFET has been explained.
By watching this video, you will learn the following topics:
1:10 What is Transfer Characteristics of JFET
2:21 How to draw Transfer Characteristics from the drain curve (For n-channel JFET)?
4:10 Calculation of drain current using the Transfer Characteristics
7:05 Transfer Characteristics of the p-channel JFET
What is Transfer Characteristics :
The Transfer characteristic is the plot which defines the relationship between the input and the output quantity (voltage and/or current) of the device.
For the JFET, it is the relationship between the input Gate to Source Voltage (Vgs) and the output drain current Id. (Keeping Voltage Vds constant)
For JFET, it is also known as the transconductance curve.
Unlike the BJT, the transfer curve for the JFET is non-linear.
Using this transfer curve, it is possible to find the biasing point of the JFET.
In this video, the transfer characteristics of the n-channel and p-channel JFET has been discussed. And using the mathematical expression of the transfer characteristics how the drain current of the JFET can be found is also discussed.
This video will be helpful to all the students of science and engineering in understanding the transfer characteristics of the JFET.
