It refers to the drain saturation current when
Max saturation the gate-source voltage (VGS) is zero.
drain current
(IDSS): It represents the maximum current that flows
through a JFET when there is no bias applied to
the gate. CHAPTER 3
Pinch-off It is the minimum Drain-Source voltage (VDS)
Voltage (VP): at which the drain current (ID) becomes
constant saturation during VGS =oV.
The VGS determines the electric field in the
channel region, thereby controlling the current CHAPTER 2
flow through the JFET.
Cut-off Voltage
VGS (off): Channel is completely cut-off.
VGS (off) represents the value of VGS that
makes drain current, ID approximately zero,
ID=0A. CHAPTER 1
