The 1st linear section of the charge curge is todo with charging the Gate-source, the flat period is countering the miller capacitor (Gate-drain). \$\endgroup\$ The field-effect transistor (FET) is a type of transistor that uses an electric field to control the flow of current in a semiconductor. FETs (JFETs or MOSFETs) are devices with three terminals: source, gate, and drain. FETs control the flow of current by the application of a voltage to the gate, which in turn alters the conductivity between the drain and source. FETs are also known as unipolar transistors since they involve single-carrier-type operation. Th… foot roma
