Abstract
Embodiments of the present disclosure relate to a power supply device, an electronic system and a method. The electronic system comprises an electronic device and the power supply device transmitting synchronization information from a satellite to the electronic system. The power supply device comprises a first modulator configured to receive a signal from a satellite and to generate a first modulated supply voltage, a level pattern of the first modulated supply voltage indicating synchronization information included in the satellite signal; and a first transformer configured to provide the first modulated supply voltage to an electronic device to enable a synchronization between the satellite and the electronic device based on the synchronization information. The electronic device demodulates the first modulated supply voltage to determine the synchronization information for synchronizing with the satellite. By using the embodiments of the disclosure, cost for manufacturing the electronic devices can be significantly reduced.
