  • Voltage-boosting stage
    Patent number: 8198756
    Abstract: The invention relates to a voltage-boosting stage (100) comprising a first capacitive voltage circuit (S1, S2, S3, S4, C0, Cb) coupled to a power supply (Vs) and providing an output voltage at an output terminal. The voltage-boosting stage further comprises a second capacitive voltage circuit (S5, S6, S7, S8, C1, Cb) coupled to a power supply (Vs) and providing another output voltage at another output terminal the output terminal and the other terminals being coupled together and further coupled to a supply terminal of a power stage (S9, S10) for implementing a two-level boosted power stage.

  • Class D amplifier
    Patent number: 8049561
    Abstract: The invention refers to an amplifier (1) comprising a switchable capacitive divider (10) for dividing a supply voltage delivered to the amplifier (1), the switchable capacitive divider being coupled to a coupling circuit (15) via a first wire and a second wire, the coupling circuit determining a connection path between said first and second wire and a first capacitor (C2) and a switchable power circuit (20).

  • VOLTAGE-BOOSTING STAGE
    Publication number: 20100038972
    Abstract: The invention relates to a voltage-boosting stage (100) comprising a first capacitive voltage circuit (S1, S2, S3, S4, CO, Cb) coupled to a power supply (Vs) and providing an output voltage at an output terminal. The voltage-boosting stage further comprises a second capacitive voltage circuit (S5, S6, S7, S8, C1, Cb) coupled to a power supply (Vs) and providing another output voltage at another output terminal the output terminal and the other terminals being coupled together and further coupled to a supply terminal of a power stage (S9, S1O) for implementing a two-level boosted power stage.
