MOSFET showing gate (G), body (B), source (S) and drain (D) terminals. The gate is separated from the body by an insulating layer (white). surface-mount packages. Operating as switches, each of these components can sustain a blocking voltage of 120nbspvolts in the ''off'' state, and can conduct a continuous current of 30 amperes in the ''on'' state, dissipating up to about 100 watts and controlling a load of over 2000 watts. A matchstick is pictured for scale. A cross-section through an nMOSFET when the gate voltage ''V''GS is below the threshold for making a conductive channel; there is little or no conduction between the terminals drain and source; the switch is off. When the gate is more positive, it attracts electrons, inducing an ''n''-type conductive channel in the substrate below the oxide, which allows electrons to flow between the ''n''-doped terminals; the switch is on. Simulation result for formation of inversion channel (electron density) and attainment of threshold voltage (IV) in a nanowire MOSFET. Note that the threshold voltage for this device lies around 0.45 V The metal-oxide-semiconductor field-effect transistor (MOSFET, MOS-FET, or MOS FET) is a type of field-effect transistor (FET), most commonly fabricated by the controlled oxidation of silicon.
In digital electronics, a NAND gate (NOT-AND) is a logic gate which produces an output which is false only if all its inputs are true; thus its output is complement to that of an AND gate.
The NOR gate is a digital logic gate that implements logical NOR - it behaves according to the truth table to the right.
Parasitic capacitance, or stray capacitance is an unavoidable and usually unwanted capacitance that exists between the parts of an electronic component or circuit simply because of their proximity to each other.
