Difference between JFET and MOSFET
JFET (Junction Gate Field-Effect Transistor):
JFET is a field-effect transistor and it is the three terminal devices. There are number of application of that, it can be used as switch, amplifier, etc. It is classified into two categories: N-Channel JFET and P-Channel JFET.
MOSFET (Metal–Oxide–Semiconductor Field-Effect Transistor):
The MOSFET is a field-effect transistor and it is a four terminal device with source(S), gate (G), drain (D) and body (B) terminals. It’s generally classified into two basic configurations: Depletion Mode MOSFET and Enhancement Mode MOSFET.
Let’s see the difference between Primary Key and Foreign Key:
|S.NO.||PRIMARY KEY||FOREIGN KEY|
|1||JFET(Junction Gate Field-Effect Transistor) is a three-terminal semiconductor device.||MOSFET(Metal–Oxide–Semiconductor Field-Effect Transistor) is a four-terminal semiconductor device.|
|2||It can only operates in the depletion mode.||It operates in both depletion mode and enhancement mode.|
|3||It has high input impedance on the order of 1010 ohms, therefore they are more sensitive towards input voltage signals.||It offers even higher input impedance than the JFETs, theredore they are more resistive.|
|4||It allows the gate leakage current on the order of 10^-9 A||While the gate leakage current for MOSFETs will be of the order of 10^-12 A.|
|5||It is relatively cheaper than MOSFETs||It is expensive one.|
|6||These are ideal for low noise applications.||These are mainly used for high noise applications.|
|7||These are less susceptible to damage because of the high input capacitance.||These are more susceptible to damage because of the metal oxide insulator.||8||Manufacturing process of JFETs is simple.||Manufacturing process of MOSFETs is complex.|
