actually I prefer a bjt
It depends. A depletion MOSFET can be used as an ehancemnet MOSFET when it is operated as an analog amplifier. However, a depletion MOSFET can't replace an enhancement MOSFET when it is operated as a digital switch. When a depletion MOSFET is used as a digital switch, since the junction between source terminal and substrate must be reverse biased, the voltage of the source terminal of an N typde transistor must be tied to Vdd, and it is completely opposite to an enhancement MOSFET. When a depletion MOSFET is used as an analog amplifer, the source terminal and the substrate are both at the same potential, just like an enhancement MOSFET.
An enhancement MOSFET doesn't conduct current across the drain to source unless a voltage is applied to the gate. When sufficient voltage is applied to the gate of the transistor, currents flows from drain to source. A MOSFET acts as a switch or amplifier in a circuit.
To switch off a MOSFET, you need to remove or reduce the gate voltage below the threshold voltage (Vgs(th)). This can be done by connecting the gate to ground or applying a negative voltage relative to the source in the case of a p-channel MOSFET. Once the gate voltage is below the threshold, the MOSFET will stop conducting, effectively turning it off. Additionally, using a pull-down resistor can help ensure the gate discharges quickly when switching off.
what is a mosfet amplifier
MOSFET is an acronym standing for Metal Oxide Semiconductor Field Effect Transistor.
FET's improve the switching frequency from KHZ to MHZ.. FET can be used as temperature sensor.. and mosfet is used as a switch..
Depletion mode MOSFET is normally on device --vlsijp
mosfet base power inverter of advantages and disaadvantages
They are both commonly used electrical switches. Some of the differences are that whereas Mosfet switches are voltage driven devices and can only switch DC current, Thyristor switches are current driven and can switch both AC and DC.
cause MOSFET are mainly the comes into category of Semiconductors, main work of inverter is to switch the contacts within microseconds, here i want to give some constructional things so it could go easy to understand the things, 1] MOSFET has a three satates, i]Deplition ii]enhancement iii]pick When the current go through the system the work of 'mft' has start as a implementing the depletion region(increasing the electrons in emitter collector junction) as and as the supply gets interrupted the MOSFET comes into work within our thinking due to high electrons consumption it goes extream fast switch the signal from one state to anther, actually MOSFET needs cery deep explination to understand it. but the main purpose is to stop reverse impulses and quike switching from one state to another.
conductiong channels
Of course it is possible to make an inverter with a p-MOSFET!
