FET Fundamentals Unit 2 – Junction FETS
Exercise 2 – JFET Characteristic Curves
EXERCISE OBJECTIVE
When you have completed this exercise, you will be able to observe the ID-VDS family of
curves by changing the gate bias. You will verify your results with an oscilloscope.
DISCUSSION
- Characteristic curves (drain current versus drain-source voltage) are used to predict the
performance of JFET. A curve is produced for several different values of VGS to generate a
family of characteristic curves.
