Abstract
A method and system for the arrangement of a power supply with an expansion card which can be connected to an electronic device and comprises at least a first and a second circuit. The power supply is arranged in at least two stages, wherein at the first stage, at least one operating voltage (Vcc) is connected to the first circuit, and at the second stage, the at least one operating voltage (Vcc) is connected to the second circuit.
Claims10
A method for supplying power to at least one expansion card component of an expansion card (1) that can be connected to an electronic device (3), the expansion card (1) having at least a first circuit (5,6,10) and a second circuit (4,9,15), the method comprising the steps that the power is supplied in at least two stages, wherein at a first one of the stages, at least one operating voltage (Vcc) is connected to the first circuit (5,6,10), and at a second one of the stages, the at least one operating voltage (Vcc) is connected to the second circuit (4,9,15), wherein the second circuit comprises a transceiver (15).
A method for supplying power to at least one expansion card component of an expansion card (1) that can be connected to an electronic device (3), the expansion card (1) having at least a first circuit (5,6,10) and a second circuit (4,9,15), the method comprising the steps that the power is supplied in at least two stages, wherein at a first one of the stages, at least one operating voltage (Vcc) is connected to the first circuit (5,6,10), and at a second one of the stages, the at least one operating voltage (Vcc) is connected to the second circuit (4,9,15), wherein the second stage is controlled by the user of the electronic device (3).
An expansion card (1) comprising means (2a, 10) for connection to an electronic device (3), wherein the expansion card (1) comprises:
- at least two circuits (5,6,10;4,9,15), and
- means (10, COR) for supplying power in at least two stages, wherein at a first one of the stages, at least one operating voltage (Vcc) is received by a first one of the circuits (5,6,10), and at a second one of the stages, the at least one operating voltage (Vcc) is received by a second one of the circuits (4,9,15), wherein the second circuit comprises a transceiver (15).
An expansion card (1) comprising means (2a, 10) for connection to an electronic device (3), wherein the expansion card (1) comprises:
- at least two circuits (5,6,10;4,9,15);
- means (10, COR) for supplying power in at least two stages, wherein at a first one of the stages, at least one operating voltage (Vcc) is received by a first one of the circuits (5,6,10), and at a second one of the stages, the at least one operating voltage (Vcc) is received by a second one of the circuits (4,9,15);
- and
- the electronic device (3) is equipped with means for conducting the second stage under control by the user of the electronic device (3).
A mobile station (1), characterised in that the mobile station (1) comprises at least two circuits (5,6,10;4,9,15), and means (10,COR) for receiving power in at least two stages, and that a transceiver unit (15) and a high-frequency power amplifier (9) of the mobile station are coupled to a second one of the circuits, wherein at a first one of the stages, at least one operating voltage (Vcc) is arranged to be coupled to the first circuit (5,6,10), and at a second one of the stages, the at least one operating voltage (Vcc) is arranged to be coupled to the second circuit (4,9,15).
