There exist various configurations for nmos MOSFET switches, as illustrated in the diagram. These include a basic NMOS switch, a bidirectional current-capable transmission gate, and a CMOS digital inverter, which can be viewed as a complementary switch. NMOS Switch Transmission Gate CMOS Switch PMOS...
Using Mosfet as a Switch A simpler option can be in the form of a mosfet switch, I have explained the circuit details of the same. As shown in the given circuit diagram the mosfet forms the main controlling device with practically no complications around it. A switch at its gate which ca...
MOSFETs, whether SiC-MOSFETs or otherwise, have a body diode between the drain and the source, as indicated in the diagram. As a consequence of the MOSFET structure, the body diode is formed by the pn junction between the source and drain, and is also called a parasitic diode or an inte...
3.7 Start-up over e-fuse and shutdown Figure 14 shows the functional block diagram of the implemented system, which comprises, in the power flow, two blocks: hot-swap and the HSC converter. The hot-swap, also known ...
Schematic Diagram for an n-Channel Power MOSFET and the Device. Figure 3 shows schematic diagram and Figure 4 shows the physical origin of the parasitic components in an n-channel power MOSFET. The parasitic JFET appearing between the two body implants restricts current flow when the depletion ...

This simple MOSFET tester does a quick job of testing both enhanced mode type N and P-channel mosfets. It checks for shorts between gate, drain and source.
As explained in the previously mentioned patent, MOSFET 44 exhibits a relatively large parasitic capacitance, represented by dotted line capacitance 70 which, especially at the low end of the UHF band, contributes to an impedance mismatch between the input of the MOSFET and resonant circuit 38 redu...
