Define threshold voltage?
Answer Posted / pankaj dubey
The threshold voltage of a MOSFET is usually defined as the
gate voltage where an inversion layer forms at the interface
between the insulating layer (oxide) and the substrate
(body) of the transistor. The purpose of the inversion
layer's forming is to allow the flow of electrons through
the gate-source junction.
