1. An integrated circuit including at least one electronic module comprising:

  • an input for introducing into the integrated circuit an external reference signal;

    a calibrating means for calibrating the at least one electronic module, wherein said calibrating means includes means to calibrate in an autonomous maimer the at least one electronic module as a function of the external reference signal introduced into the integrated circuit via the input to obtain final calibrating parameters when an output signal of the electronic module is equal to the external reference signal;

    a storage means for storing the final calibrating parameters, the stored calibrating parameters having an associated signature stored therewith; and

    a signature detection means for detecting the associated signature presence in the storage means such that when a signal is applied to the input, the presence of said associated signature allows the stored calibrating parameters to be transmitted to the at least one electronic module.
