JFET(Junction Field Effect Transistor) VS MOSFET (Metal Oxide Semiconductor FET)

                    

                    JFET                                                                 MOSFET

• Operates only in depletion mode                     .Operates  in depletion and Enhancement mode
• Input resistance is high (10^8 Ohms)                 . Very high input resistance (10^9 - 10^18) 
• High drain resistance                                        .  Low drain resistance 
• Leakage current is more (10^-9A)                      .Less leakage current (10^-12A) 
• Large gate current                                              . Lower gate current  
• Posses some offset voltage                                 . Zero offset voltage

Note: Depletion MOSFET is also called dual mode MOSFET
