Abstract
A dual supply device having a reference terminal, an input terminal for the application of a substantially constant input voltage relative to the reference terminal, a first output terminal for supplying a first supply voltage different from the input voltage, a second output terminal for supplying a second supply voltage substantially opposite to the first supply voltage a direct-current/direct-current converter connected between the input terminal and the first output terminal for converting the input voltage into the first supply voltage, and a capacitive translator connected between the first and second output terminals for translating the first supply voltage into the second supply voltage.
