Abstract: An integrated electronic device includes a core having a first terminal and a second terminal. The core includes a first branch with a first diode-connected bipolar transistor coupled in series to a first resistor between the first terminal and a reference terminal intended to be supplied with a reference voltage, and a second branch with a second diode-connected bipolar transistor coupled between the second terminal and the reference terminal. The second diode-connected bipolar transistor has a current density higher than the first diode-connected bipolar transistor. The core also includes a first resistive network coupled between a base of the first diode-connected bipolar transistor and the reference terminal. An equalizer is configured to equalize potentials of the first terminal and of the second terminal and a voltage generator is coupled to the first and second terminals of the core and configured to generate the bandgap voltage.

Abstract: An electronic circuit includes a switch coupled between an input terminal intended to receive a first voltage and an output terminal coupled to a decoupling capacitor and intended to also be coupled to a load. A comparison stage is configured to compare the first voltage and a second voltage that is present at the output terminal. A first adjustment stage is configured to limit a positive inrush current flowing between the input terminal and the output terminal and a second adjustment stage is configured to limit a negative inrush current flowing between the output terminal and the input terminal. A control circuit is configured to activate either the first adjustment stage or the second adjustment stage as a function of a result of the comparison.
