Abstract

A power management controller circuit with switched capacitor mode down regulator and battery charger block for semi-active RFED tags was proposed and fabricated. The main purposes of the proposed switched capacitor mode down regulator and battery charger block are to reduce standby current and to provide a self-controlled thin film battery charger by detecting the received RF power, respectively. Fabricated chip area is 360,000um² and measured standby current was about 1.3uA. To further reduction of standby current, a wake-up circuit has to be included in the power management controller.
