What is the primary difference between a JFET and an E-MOSFET?
What is the primary difference between a JFET and an E-MOSFET?
- JFETs have a higher input impedance than E-MOSFETs.
- JFETs use a p-n junction to control the flow of current, while E-MOSFETs use an electric field to control the flow of current. (correct)
- JFETs are more reliable and have a longer lifespan than E-MOSFETs.
- E-MOSFETs have a higher gain than JFETs.
