Comparison between pinch off and cut off voltage
hi,
When we compute the pinch off voltage for an n channel JFET, we always do it by keeping Vgs = 0 and then the value of Vds for which the channel conductivity ceases is noted. Now when we try to find out the cut-off voltage Vgs(off) it is the gate source voltage for which the channel ceases its conduction. My question is do we keep Vds = 0 during the calculation of cut-off voltage.
