explain the basic characteristics of the MOSFET?
Answers
MOSFETs are tri-terminal, unipolar, voltage-controlled, high input impedance devices which form an integral part of vast variety of electronic circuits. These devices can be classified into two types viz., depletion-type and enhancement-type, depending on whether they possess a channel in their default state or no, respectively. Further, each of them can be either p-channel or n-channel devices as they can have their conduction current due to holes or electrons respectively. However inspite of their structural difference, all of them are seen to work on a common basic principle which is explained in detail in the article “MOSFET and its Working“. This further implies that all of them exhibit almost similar characteristic curves, but for differing voltage values.
