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.
