Here’s a simple FET circuit that lets you switch power to, say, a USB port, kind of like a valve that interrupts the current flow. This circuit uses a P-FET – to turn the power on, open the ...

A simple FET radio receiver circuit showing FET biasing ... no standing gate current after an initial surge. A MOSFET power switch can thus be built requiring much less in the way of drive ...

The introduction of monolithic circuits, dealt with in more detail in Chapter 10 ... response with zero d.c. bias power when using small signal devices. Figure 9.1: Various FET Switch Configurations ...

The mosfet is off if the input voltage is normally less than \(2.0 V\). By looking at a circuit diagram of a transistor switching circuit, you should be able to say what the circuit is used for ...
