Abstract
There is provided a power conditioning circuit including positive and negative power input nodes. An inductor includes a first terminal connected to a positive power input node and a second terminal connected to a positive power output node, the inductor allowing the voltage at the positive power output node to be modulated by data that is sent through a communication interface. A first node is present between the second terminal of the inductor and the positive power output node, and a clamping circuit is connected at the first node to a second node. The clamping circuit is configured to clamp a voltage increase across the inductor to less than a maximum increase. The second node is configured to be continuously held at a voltage higher than the voltage of the first terminal of the inductor.
