power supply for RFID transponder
Abstract
A charge accumulation circuit (103,300) having a structure in which a capacitor (202) is divided into a plurality of pieces and the divided capacitors (301) are connected in parallel through switches (302) is provided. The charge accumulation circuit controls the switch provided between the capacitors and thus can dynamically vary electrostatic capacitance of the charge accumulation circuit which applies a voltage to a constant voltage circuit (104).
