Given a JFET with a maximum VGS of -4V and a drain current that becomes constant at a VDS of 10V, explain the practical implications of operating near pinch-off for an amplifier circuit.
💡 Hint: Consider the role of the JFET in maintaining signal integrity in circuits.
If a p-channel JFET has a gate cut-off voltage of -3V, determine how the gate voltage affects current flow compared to an n-channel JFET with a cut-off of 3V.
💡 Hint: Reflect on how charge carriers affect operational parameters.
