Provided is a contactless electronic system configured for contactless communications with a reader over an electromagnetic field and comprising a power supply, a current monitor, a processing system comprising a hardware processor configured for performing operations, a dynamic extra current loader and a clock generator. The current monitor is configured for determining maximal current Imax that can be provided by the power supply to the processing system from the electromagnetic field, and is configured for comparing, during an execution phase of said hardware processor, said determined maximal current Imax and a current drawn by the processing system.

Contactless system and method for reducing electromagnetic disturbances of said contactless system

Provided is a contactless electronic system configured for contactless communications with a reader over an electromagnetic field and comprising a power supply, a current monitor, a processing system comprising a hardware processor configured for performing operations, a dynamic extra current loader and a clock generator, wherein the power supply includes a clamp circuit, and wherein, continuously until the end of an execution phase of said hardware processor. The current monitor is configured for determining the maximal current Imax that can be provided by the power supply to the processing system from the electromagnetic field by comparing a current into the clamp circuit to at least one predetermined threshold. Other embodiments disclosed.
