ABSTRACT:
A charge pump stage of an RFID transponder includes an RF node, a capacitor bank, a plurality of current-biased rectifier stages, a DC bus, a programmable current source and a control circuit. The RF node provides an RF signal. The capacitor bank has a selectable capacitance and is electrically coupled to the RF node. The plurality of current-biased rectifier stages receives the RF signal from the RF node. The plurality of current-biased rectifier stages provides a DC output. The DC bus receives the DC output from the plurality of rectifier stages and provides a supply voltage. The programmable current source provides a plurality of current bias signals for each of the plurality of current-biased rectifier stages. The control circuit is in electrical communication with the capacitor bank and the programmable current source. The control circuit selects the selectable capacitance of the capacitor bank and programs the current source.
