What is D-MOSFET ?

Depletion mode metal oxide semiconductor field effect transistor.

It's a plastic foam that has been saturated with carbon particles, allowing it to dissipate static charges. Due to the high carbon content, it is usually black in color. It is frequently used for packaging or storing static-sensitive electronic components, such as MOSFET transistors and integrated circuits.

If it is p type d-mosfet than the n+ region is formed. Since, the mobility of the electrons are more than the holes the input impedance is high.

Since at higher frequencies, the input impedance of MOSFETS lowers in value, to compensate for the loss of high input impedance MOSFETS can be connected in series such that the impedance of each MOSFET adds up with each other.
