What is the advantage of MOSFET over BJT?
They are portable, use low power, draw no current and are compatible with silicon processing technology. Their lack of gate current results in high input impedance. One additional major advantage of MOSFET over BJT is that it forms the basis of a circuit with switches of analog signals.
What is the advantage of a MOSFET switch?
Advantages of MOSFET MOSFETs provide greater efficiency while operating at lower voltages. Absence of gate current results in high input impedance producing high switching speed. They operate at lower power and draws no current.
Which of the following choices is an advantage of a MOSFET over a BJT in an RF amplifier?
The obvious advantage of a MOSFET is its very low drain-source on state voltage drop because of a very low drain-source on state resistance (RDSON). For a BJT, the collector-emitter saturation voltage may vary with the level of the base current and the collector current or simply the load.
What are the advantages of MOSFET over BJT?
mosfet consumes much less power when switching at high frequency because of its faster switching speed. this is due to the fact that the mosfet leads by grid-oxide controlled field effect and not by electron / hole recombination (which is slow) as in bjt. The gate control circuit is much simpler in the mosfets.
What is the difference between a transistor and a MOSFET?
Paralleling the MOSFET is easier than that of the transistors to handle a high current, because the MOSFET has a positive coefficient of resistance, unlike the bjts. Bjts have a negative resistance temperature coefficient and therefore suffer from a thermal runaway where all the current is deflected in a single bjt when it is paralleled.
What are the advantages of MOSFET over bipolar transistors?
In MOSFET, the circuit like gate control is very simpler There are numerous reasons that stand out. Fewer Conduction Losses. A bipolar junction transistor includes a stable saturation voltage drop like 0.7 V, whereas the MOSFET includes a 0.001-ohm on-resistance that leads to fewer power losses. High Input Impedance
What is the gate current of a MOSFET?
The MOSFET is a voltage-controlled device and it doesn’t include gate current almost. The gate works like a value capacitor and it is a significant benefit in the applications of switching & high current because the gain of the power BJTs has medium to low, that needs high base currents to produce high currents.
