V-I Characteristics of JFET
The voltage VGS applied to the Gate controls the current flowing between the Drain and the Source terminals. VGS term as the voltage applied between the Gate and the Source whereas VDS refers to the voltage applied between the Drain and the Source.
Junction Field Effect Transistor is a voltage controlled device, “NO current flows into the gate!” then the Source current ( IS ) flowing out of the device equals the Drain current flowing into it and therefore ( ID = IS ).
The characteristics curves, as shown above, have four different regions of operation for a JFET and these regions are given as:
- Ohmic Region– When VGS = 0 the depletion layer of the channel is very small and in this region, JFET acts like a voltage controlled resistor.
- Cut-off Region– This is also known as the pinch-off region in this region Gate voltage, VGS is sufficient to cause the JFET to act as an open circuit as the channel resistance is at maximum.
- Saturation or Active Region– In this region, JFET becomes a good conductor and is controlled by the Gate-Source voltage, (VGS) while the Drain-Source voltage, (VDS) has very small or no effect.
- Breakdown Region– in this region the voltage between the Drain and the Source, (VDS) is high enough to cause the JFET’s resistive channel to break down and pass uncontrolled maximum current.
The characteristics curves for a P-channel junction field effect transistor are similar to n channel characteristics shown above, except that the Drain current ID decreases with an increasing positive Gate-Source voltage, VGS.
For normal operation, the Drain current is zero when VGS = VP., VGS is biased to be somewhere between VP and 0.so that we can calculate the Drain current, ID for any given bias point in the saturation or active region as follows:
Drain current in the active region.
