What is semiconductor triode?

It can be either a Bipolar Junction Transistor (NPN or PNP) or a Field Effect Transistor (N channel JFET, P channel JFET, N channel MOSFET, or P channel MOSFET).


What are the classifications of MOSFET?

MOSFET stands for Metal Oxide Semiconductor Field Effect Transistor, It is broadly Classified into Depletion type MOSFETS and Enhancement type MOSFETS. Depletion type MOSFETS are further classified into P-Channel and N-Channel Depletion type MOSFET, Similarly Enhancement type MOSFETS are further classified into P-Channel and N-Channel Enhancement type MOSFET.


Is it possible to make the inverter with p-channel MOSFET?

Of course it is possible to make an inverter with a p-MOSFET!


Construction of mosfet in depletion region?

To make a depletion MOSFET, the channel must be doped with carriers; this is in total opposite to an enhancement MOSFET which avoids carriers in the channel at all cost. (because the carriers in the channel become the subthreshold leakage current) Since you need to pinch the channel against the substrate to guarantee to turn off the channel completely, there must be a reverse bias between the substrate and the source terminal. As a result, the source terminal of an N type depletion MOSFET must be tied to Vdd. This is also a complete opposite to enhancement MOSFET. In order to turn off the channel quickly, the carriers in the channel of depletion MOSFET are usually planted shallowly. This is a drastically different from enhancement MOSFET that carriers must be planted deeply into source terminal in order to support a large diffuse current. The construction of depletion MOSFET thus requires far less diffusion time than enhancement MOSFET.

What are the differences betweeen e-mosfet and d-mosfet?

An e-mosfet is and "enhancement" mosfet. A d-mosfet is a "depletion" mosfet. These essentially show what mode the mosfet operates in when a voltage is applied to the gate. . An enhancement mode mosfet is normally non-conducting but conducts when the channel is enhanced by applying a voltage to the gate and pulling carriers into the channel. A depletion mode mosfet normally conducts but becomes more and more non-conducting as carriers are depleted or pulled out of the channel by applying a voltage. The polarity of the voltage depends on whether it is an N channel or P channel. P channel uses positively doped silicon while N channel uses negatively doped silicon. N channel fets are used wherever possible because N material conducts better than P material. There are basically two types of fet, the jfet and the mosfet. The jfet uses a single junction to control the channel hence draws some current. Bipolar transistors use two junctions. In the mosfet (Metal Oxide Semiconducting Field Effect Transistor) there is no such junction hence draw so little current for control purposes it can be regarded as zero. The gate is isolated from the channel by a very thin layer of metal oxide (usually chromium dioxide). An enhacement mode mosfet can be turned on by applying a voltage then removing the wire to the gate. The channel will then remain conducting for some time.

What is depletion mosfet?

A depletion mode MOSFET is a FET that is on with no gate bias, and requires a negative bias (with respect to the source) to stop conducting. The channel is normally conductive and with a negative gate bias the channel becomes "depleted" of charge carriers, hence the name depletion mode MOSFET. This is contrary to enhancement type MOSFET's that are non conductive with zero volts gate bias and become conductive when there is a positive bias on their gate.


The value of gate voltage for the operation of enhancement of only N channel MOSFET has to be high positive?

yes.
