Suppose we have two voltages V1 and V2 how can we store the voltage difference
(V1-V2) on a given capacitor?
I tried charging the top plate of the capacitor to V1 and then charged the bottom plate of the capacitor to V2. but the value of the voltage across the capacitor is not V1-V2, how can we do this?
Basically I want to perform subtraction of 2 voltages, with a simple circuit which does not consume much power and area
