What is P-Channel MOSFET?

A MOSFET is created when a substrate with a light amount of N-type doping is linked to two materials with a high amount of doping of the P-type. Doping refers to adding a certain quantity or concentration of an impure substance to the atom.

How does P-Channel MOSFET work?

The operation of the P-channel MOSFET is predicated on the produced or existing channel and the concentration of most charge carriers within the channel. In this particular instance, the holes constitute most of the carriers.

P Channel with Enhancement MOSFET

The n-substrate, which is mildly doped, was used in the design of this MOSFET. The two highly doped p-type materials are separated from one another by the length (L). The length of the channel is denoted by the number L.

The substrate is given a thin coating of type silicon dioxide, which is then placed on top. The layer in question is typically referred to as the dielectric layer. The two P types each make up the circuit’s source or drain. The gate terminal is made of aluminium plating placed on the dielectric material. The ground connection is made at the MOSFET’s source and body.

The gate terminal has been subjected to a voltage in the negative range. Because of the effect that capacitance has, the positive concentration of charges eventually becomes settled lower at the layer that is known as dielectric. Because of the repulsive forces, the electrons at the n substrate shift, and the value of the uncovered positive ions layer may be discovered there. This occurs because of repulsive forces. A bond is formed when a minority carrier, such as a hole, in an n-type substrate, joins with a small number of the substrate’s electrons.

However, continued application of the negative voltage destroys the covalent bonds, and, as a result, the pairs that were generated between electrons and holes also fall apart. This formation causes the development of holes, which in turn causes an increase in the carrier concentration of holes in the channel, which leads to an increase in the concentration of holes. Since the channel becomes conductive when a negative voltage is given to the drain terminal, the transistor can carry out its function of allowing current to flow through it.

P Channel Depletion MOSFET

When contrasted with the production of n channel depletion in a MOSFET, the formation of p channel depletion occurs exactly in reverse. The impurities of the p-type that are present in it are responsible for the pre-build of the channel in this case. When a negative voltage value is supplied at the terminal gate, free holes, which represent the minority carriers in an n-type semiconductor, are drawn into the channel of positive-type impurity ions. This happens because the free holes represent the minority carriers. Under these circumstances, when a drain terminal is reverse biased, the device begins conducting; however, as the negative voltage in the drain terminal is increased, this causes the depletion layer to form.

The concentration of the layer that is created as a result of the positive ions has a direct effect on this region. The magnitude of the value of the conductivity of the channel is influenced by the breadth of the zone of depletion. The current that flows through the terminal can be made to behave in a desired manner by manipulating the region’s voltage value. In conclusion, both the gate and the drain exhibit a negative polarity, whilst the source maintains its value of zero throughout the process.
