Explain and Compare JFET's and MOSFET's?
Submitted by: AdministratorComparison of JFET's and MOSFET's:
• JFET's can only be operated in the depletion mode whereas MOSFET's can be operated in either depletion or in enhancement mode. In a JFET, if the gate is forward-biased, excess-carrier injunction occurs and the gate-current is substantial.
• MOSFET's have input impedance much higher than that of JFET's. Thus is due to negligible small leakage current.
• JFET's have characteristic curves more flat than that of MOSFET is indicating a higher drain resistance.
• When JFET is operated with a reverse-bias on the junction, the gate-current IG is larger than it would be in a comparable MOSFET.
