WebApr 26, 2024 · The gate-source and gate-drain junctions are PN junctions. In one direction, you will measure a diode drop, the other will measure open. This allows you to determine if you are dealing with an n-channel or a p-channel JFET: if a positive gate voltage leads to a diode drop, it's an n-channel device. WebAug 28, 2024 · FETs come in a variety of flavors depending on their channel doping (leading to enhancement and depletion modes) and gate types, as seen in Figure 10.2. 2. The two FET types are junction field effect transistors (JFETs) and metal oxide semiconductor field effect transistors (MOSFETs). Figure 10.2. 1 The n-channel enhancement mode MOSFET …
