... transistors must be 1.3 V about VSS, since the source of the top left transistor is at 0.65 V above VSS. The top right transistor’s source must also be around 0.65 V to maintain the same Vgs voltage. Thus, the output drain can be no more than Vt volts below the gate, and so must be 1.3 V-0.5 V=0.8 V ...

... The first step in the solution is to simplify the circuit. Note that the 10[W] and 13[W] resistors are effectively in series with an open circuit, thus no current flows through them. As a result, they have no voltage across them. They can be ignored. Also, the 75[W] resistor is in parallel with a sh ...

Islanding

Islanding refers to the condition in which a distributed generator (DG) continues to power a location even though electrical grid power from the electric utility is no longer present. Islanding can be dangerous to utility workers, who may not realize that a circuit is still powered, and it may prevent automatic re-connection of devices. For that reason, distributed generators must detect islanding and immediately stop producing power; this is referred to as anti-islanding.The common example of islanding is a grid supply line that has solar panels attached to it. In the case of a blackout, the solar panels will continue to deliver power as long as irradiance is sufficient. In this case, the supply line becomes an ""island"" with power surrounded by a ""sea"" of unpowered lines. For this reason, solar inverters that are designed to supply power to the grid are generally required to have some sort of automatic anti-islanding circuitry in them.In intentional islanding, the generator disconnects from the grid, and forces the distributed generator to power the local circuit. This is often used as a power backup system for buildings that normally sell their excess power to the grid.
