Patent ID: 6914473

Claim:
A circuit arrangement for generating at least one voltage value, which circuit arrangement includes a subvoltage generating unit and a voltage multiplier, the subvoltage generating unit being arranged to switch the voltage multiplier to a direct mode in order to control the voltage multiplier during a start time; the subvoltage generating unit comprising a plurality of intermediate nodes, each intermediate node formed by a series connection of a pair of resistors, and a plurality of switches, each switch coupled to one of the plurality of intermediate nodes; wherein when the voltage multiplier is in direct mode the voltage multiplier is configured to connect a power supply node to an output of the voltage multiplier, and when the voltage multiplier is not in direct mode, the voltage multiplier is configured to disconnect the power supply node from the output of the voltage multiplier, and to connect the output of the voltage multiplier to an internal node for providing an internally generated output voltage.
