A certain JFET data sheet gives VGS(off) = -4 V. The pinch-off voltage Vp is _____________?
Correct answer: A. +4 V
- A. +4 V
- B. -4 V
- C. dependent on VGS
- D. data insufficient
Explanation
For the usual JFET convention, the pinch-off voltage Vp is the positive magnitude of the negative cutoff voltage: Vp = |VGS(off)| = 4 V. The corresponding gate cutoff voltage is -4 V.
