Abstract
An embodiment electronic circuit power supply device is configured to: flow, through a first conductor connected to a node, a first current that is an image of a second current consumed by the electronic circuit; flow a third current through a second conductor connected to the node; regulate a potential of the node to a constant value by acting on the third current; flow a fourth constant current through a third conductor connected to the node; and consume a fifth current that is an image of the third current.
