Sr.No	BJT	MOSFET
1	Current flows due to both majority and minority carriers.	Current flows due to majority carriers.
2	It has negative temperature coefficient	It has positive temperature coefficient
3	Switching frequency is lower than MOSFET	Switching frequency is higher
4	Operation depend upon current at the base	Operation depends upon the voltage at the insulated gate
5	Transfer Characteristics is linear	Transfer Characteristics is non-linear
6	Use for low current and power application	Use for high power function
7	Low input resistance	High,input resistance
8	Rarely used in digital VLSI design	Widely used in digital VLSI design
9	Difficult to fabricate and occupy more space	Much easier to fabricate and occupy less space
10	It’s a current controlled current device	Its voltage controlled current device.
