WebApr 12, 2024 · Operation of MOSFET. The function of MOSFETs (Metal-Oxide-Semiconductor Field-Effect Transistors) is reliant on the mechanism by which the gate voltage manipulates the current flow between the source and drain regions. There are two main types of MOSFETs: enhancement-mode MOSFETs and depletion-mode MOSFETs. WebSo, to thoroughly test a JFET with a multimeter, you’ll have to build a small circuit that switches the device on/off. Thus, allowing you to measure both on and off modes. Also, …
