A charge recycling dual‐rail voltage supply is proposed for battery‐powered radio frequency identification tags. By utilising a capacitor voltage divider and recycling charge from the upper to the lower rail with a virtual ground balancing circuit, an implicit on‐chip DC–DC converter can be achieved. The proposed dual voltage scheme provides an effective way of reducing power consumption both in sleep and active modes of operation.
