BJT and MOSFET
BJT
- BJT is NPN or PNP.
- BJT is a current controlled device.
- The temperature coefficient of BJT is negative.
- The input resistance of BJT is low.
- The switching speed of BJT is slower.
- BJT is not expensive.
- The current output of BJT can be controlled through the input base current.
- it is used for the low current application.
MOSFET
- MOSFET is P-type or N-type.
- MOSFET is a voltage controlled device.
- The temperature coefficient of MOSFET is positive.
- The input resistance of MOSFET is high.
- The switching speed of MOSFET is higher.
- BJT is not expensive.
- The current output of BJT can be controlled through the input base current.
- it is used for the low current application.
