Describe the principle of field effect transistors (FET) with control junction (JFET) and with structure “metal-oxide-semiconductor”(MOSFET). Describe pulse mode of MOSFET with inducted n-channel in switching circuit with Common Source (CS) using output VAC`s and temporal waveform of input and output signals.Determine the mode of considering FET (depleted, enhanced or compatible). Is this normally close or open FET? Where is the difference between determination of cutoff voltage and theshold voltage?
