A switch that is opened or closed. See switch
A group of transistors that makes up an AND, OR or NOT Boolean logic gate. See Boolean gates
, logic gate
and gate array
In a field effect transistor (FET), the gate is the element that acts as a trigger to cause the transistor to switch. In a bipolar transistor, the gate is called the "base." See transistor
The Gate in an NMOS Transistor
The gate is the trigger line. When pulsed, an electromagnetic field causes the switch to close.
