Junction Field Effect Transistors (JFETs)


More Realistic IC JFET Transistor

JFET Applets:

As a review of how the size of the depletion layer varies with voltage in a back biased junction let's look at the applet  Space charge and electric field in biased PN junction.

The Junction Field Effect Transistor (JFET) Applet shows a simulation of channel "pinch off" and examples of resultant the output characteristics.

The following are "freeze frame" series from the Junction Field Effect Transistor (JFET) Applet to the demonstrate operation of JFETs.

Series 1: Operation at constant gate voltage

 
Series 2: Operation at constant drain-source voltage

 
Series 3: Operation at constant drain-source voltage
