Abstract
An electronic device includes a power supply terminal, a voltage regulator connected to the power supply terminal, an electronic module connected to the voltage regulator, and a compensation circuit configured to receive an auxiliary current generated by the voltage regulator and being equal to a first fraction of the electronic module current. The compensation circuit includes a current source configured to supply a source current to a cold point, and a compensation stage connected to the power supply terminal and being traversed by an intermediate current equal to a difference between the source current and the auxiliary current and by a complementary current equal to the intermediate current multiplied by an inverse multiplication factor of the first fraction.
