I have a variable voltage source and I need to have a voltage reference that is always -6v relative to the variable voltage source.
The catch is my new voltage reference can't draw any current from the variable voltage source in order to get its voltage drop but I must be able to draw current from the new voltage reference itself.
I can't think of any ways to get a -6v offset without drawing current from the variable voltage source via LEDs or something.
