Abstract:
An embodiment of a discharge circuit comprises an output circuit with one output connected to an electrical load to absorb a discharge current given by the load when a logic signal commands a discharge of the load. The discharge circuit also comprises a control circuit to give the output circuit an appropriate control signal so that a slope of an output potential of the output circuit diminishes gradually when the logic signal commands a discharge of the load. Limiting the slope of the output potential gradually (and not suddenly) may limit the electromagnetic radiation generated by these variations.
