Abstract
For a longer working distance between passive tags and the reader, the ferroelectric based technologies are proposed in UHF (860-960 MHz) band transponder. The small ferroelectric capacitor layout area with a stacked capacitor structure over circuit region and a large dielectric permittivity of 250 to 500 and small 1T1C cell array layout area with simple 2T2C based reference scheme allow small chip size. The low operation voltage of 1.5 V to 2.0 V without high voltage boosting scheme also contribute to small power consumption and low cost.
