Abstract
An embodiment of a current measuring device, defined by a gain, including an amplification module including an input for receiving a control signal, an input connected to an output node, brought to an output potential and traversed by an output current, a feedback node traversed by a mirror current associated with the output current by a proportionality coefficient equal to the gain, and an output traversed by the mirror current, and capable of bringing the feedback node to the output potential in response to the control signal. The measuring device also includes a gain modification module, mounted between the first potential and the feedback node, including at least one input for receiving an activation signal, and capable of modifying the value of the gain in response to an activation signal.
