An FET amplifier is an amplifier that uses one or more field-effect transistors (FETs). The most common type of FET amplifier is the MOSFET amplifier, which uses metal–oxide–semiconductor FETs (MOSFETs). The main advantage of a FET used for amplification is that it has very high input impedance and low … Skatīt vairāk The transconductance is given by $${\displaystyle g_{m}={I_{\mathrm {D} } \over V_{\mathrm {GS} }}}$$ On rearranging, we get Skatīt vairāk There are three types of FET amplifiers, depending on which terminal is the common input and output. (This is similar to a bipolar junction transistor (BJT) amplifier.)
