Abstract

A charge recycling dual-rail voltage supply is proposed for batterypowered 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.
