I have a device in a DC circuit that calls for decoupling capacitors on VIN and VOUT. The circuit is powered by two batteries in series. The above device is hooked up in parallel to the second battery with the device ground connected to the node shared between the two batteries like so:
Should I connect my decoupling capacitors to the node shared by the the negative terminal of vdc2 or the node shared by the negative terminal vdc1? Does it matter? Topologically, with the real world circuit, it would be easier to connect to that bottom most node shared by the negative terminal of vdc1, but I'm not sure if having the potential of both batteries across the caps will cause bad things to happen...
Thank you!
