WebIn 1959 M. M. (John) Atalla and Dawon Kahng at Bell Labs achieved the first successful insulated-gate field-effect transistor (FET), which had been long anticipated by Lilienfeld, Heil, Shockley and others (1926 Milestone) by overcoming the "surface states" that blocked electric fields from penetrating into the semiconductor material. WebBasics of the MOSFET The MOSFET Operation The Experiment The MOS Transistor Operating Regions of the MOSFET TheMOSTransistor Once the threshold has been crossed, we need to make the electrons move, i.e. set up a current. For this, we need two more terminals- Source (S) and Drain (D), and a potential across them to control the …

The dV/dt turn-on was due to the inherent parasitic NPN transistor incorporated within the MOSFET, shown

Transconductance is a critical parameter strictly connected with the threshold voltage (V TH) of MOSETs and both are related to the size of the gate channel. The formula for deriving the transconductance of a MOSFET from I-V measurements is: g m =. ΔI D.
The Early effect, named after its discoverer James M. Early, is the variation in the effective width of the base in a bipolar junction transistor (BJT) due to a variation in the applied base-to-collector voltage. A greater reverse bias across the collector–base junction, for example, increases the collector–base depletion width, thereby decreasing the width of the charge carrier portion of the base.
