Hi pebe,
well there's a bit of confusion here about what i meant to ask.
I do not intend to disrespect your reply.
I just want to clarify the definitions as i have learnt them:
pinch-off voltage is the minimum drain-source voltage at which the drain current essentially becomes constant.
gate-source cutoff voltage is the gate source voltage where the channel is completely cut off and the drain current becomes zero.
plz do correct me if i am wrong somewhere or if there is some conceptual
error.
