How can you make a mosfet switch at a voltage of your choice?
Typically I'm looking to switch on a relay or very small resistive load at 2.8volts
My rail will be 12vdc the gate source is related to the rail supply but I do need resolution of .1volt. Some sort of potentiometer will be needed to adjust the gate threshold as 2.8 might not be the voltage I need transition at
