mosfets come in 2 shape
1.round shaped(like bjt):hold it such that the pins face upwards and the knoch perpendicular to your eyes,then name pins as G,D,S in anticlock wise direction.
2.almost squre shaped.hold it perpendicular to your face ,then name them G,D,S from left to right

Why mosfet is called mosfet?
MOSFET is an acronym standing for Metal Oxide Semiconductor Field Effect Transistor.
Advantages and disadvantages of depletion MOSFET?
Since the logic operations of depletion MOSFET is the opposite to the enhancement MOSFET, the depletion MOSFET produces positive logic circuits, such as, buffer, AND, and OR. The most significant advantage of the positive logic circuits is that it can produce positive feedback easily so that a single depletion MOSFET can become a memory cell. In contrast, you will need at least two enhancement MOSFET transistor to produce the positive feedback to build a memory cell. The other advantages of depletion MOSFET are that it is free from sub-threshold leakage current and gate-oxide leakage current. Since there is always a potential difference of Vdd between the gate terminal and channel for an enhancement MOSFET to cause the gate-oxide leakage current, the gate oxide leakage current is unavoidable when the transistor shrinks in size and oxide layer becomes thinner. The depletion MOSFET does not have this problem because there is no potential difference between the gate and channel. As a enhancement MOSFET shrinking in size, there is no way to stop the subthreshold leakage current diffused across from source to drain because the drain and source terminals are closer physically. This is not a problem for depletion MOSFET because a pinched channel will stop the diffusion current completely. The depletion MOSFET is the ideal, perfect transistor. The only disadvantage of depletion MOSFET is its inability to produce negative logic operations.

Can transistors have four legs?
In case of a bipolar junction transistor, we have only three terminals (legs). They are emitter, base and collector. But, in case of a MOSFET (metal oxide semiconductor field effect transistor), we can have four legs. They are source, drain, gate and substrate. The substrate is not being shown in some notations of MOSFET. But it does exist. Hence, a MOSFET has four legs.
How e mosfet works?
A MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) works by controlling the flow of electricity between the source and drain terminals using an electric field applied to the gate terminal. When a voltage is applied to the gate terminal, it creates an electric field that either allows or blocks the flow of current between the source and drain terminals, acting as a switch or amplifier in electronic circuits.

What are electrodes called in a MOSFET transistor?
The terminals on a MOSFET are called the "Source", "Drain", and "Gate". Just as with a bipolar junction transistor (BJT) the direction of current flow will be based on the doping configuration of the semiconductor. In a MOSFET, the doping configuration can be either n-channel or p-channel, but with MOSFETS, they also come in a "normally on" or "normally off" configuration, which is specified by being either "depletion mode" or "enhancement mode", respectively.

Can depletion mosfet act as enhancement mosfet?
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.
Difference between de-mosfets e-mosfets and jfets?
The basic theory of operation is the same, but the device structure is different. With both a MOSFET and a JFET, a conductive channel is established between two terminals (the drain and the source). The structure of the gate terminal makes the difference between the two. In a MOSFET, the metal gate is separated from the channel by an insulator (the O in MOSFET means Oxide, the insulator). In a JFET the gate is a doped region essentially within the conductive channel.
