Hi guys,
I have a MOSFET (n-type) which i want to use to control an led..
I have the drain connected to 5v
the source is connected to the LED (positve end)
and I will be using 5v to control the led at the gate...
however, having 5v at the gate gives me a very dim light...
i looked at the connections and calculated that I am in the Saturation region ( Vds is greater than Vgs - Vt )..(should I have it such that I operate in the linear if i want to use the FET as a switch? and if so , how do i connect it to properly bias the FET to work as a switch ? )
thanks guys
