Abstract :
A series voltage regulator for long-distance passive microwave RFID (RadioFrequency IDentification) transponders, based on subthreshold CMOS circuits, is presented. It is shown that for a voltage regulator that supplies power to subthreshold circuits, temperature compensation would actually represent a disadvantage, while a proper built-in nonzero temperature coefficient can strongly suppress the temperature dependence of the overall subthreshold circuit performance. Implementation and experimental results are discussed
