Abstract
A method and a device, the device has ground voltage elevation compensation capabilities and includes: multiple current consuming components; a positive voltage supply input; a negative voltage supply input; and a compensation circuit, coupled to the negative voltage supply input and to a grounding element; wherein the compensation circuit is adapted to detect a ground voltage elevation resulting from a flow of excess consumption current through the grounding element, and in response couple the negative voltage supply input to the grounding element; wherein the excess current flows through the grounding element due to an increment in a current consumption of a current consuming element of the device.
