  • Patent number: 11522360
    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.

  • Patent number: 9933797
    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.

  • Patent number: 9423809
    Abstract: The present invention concerns a low dropout (LDO) regulator of regulating an output signal, the LDO regulator comprising an input stage (15) and an output stage (17), the input stage being adapted to receive a reference signal (VREF) and a feed-back signal (VF) depending on an output signal (VOUT), and to output an intermediate signal based on the feedback signal and on the reference signal, wherein the LDO regulator further comprises a gain stage (16) having a given gain value, which is configurable and wherein the output signal is regulated based on the gain value of the gain stage and on the intermediate signal.
