Stacked Power Supply for Reduced Current Consumption

摘要

A circuit arrangement comprising a first capacitor and a second capacitor which are arranged in series between a high potential and a low potential is described. The circuit arrangement comprises first power consuming circuitry which is arranged in parallel to the first capacitor. The first power consuming circuitry (113) consumes electrical power at a first voltage. The circuit arrangement comprises second power consuming circuitry which is arranged in parallel to the second capacitor . The second power consuming circuitry consumes electrical power at a second voltage, wherein a magnitude of the sum of the first voltage and the second voltage is smaller than an absolute difference between the high potential and the low potential. The circuit arrangement sets a voltage at the first capacitor in accordance to the first voltage and to set a voltage at the second capacitor in accordance to the second voltage.
