Abstract :
A dual-power-path (DPP) RF-DC topology is employed to design the power management unit for an EPC C1 G2 RFID tag using a 0.18µm CMOS process with 7 output voltages for signal processing blocks and OTP memory. The DPP technique splits the rectifier and reconfigures the RF-DC circuits depending on the state of input power, which saves storage capacitor size without sacrificing efficiency, or alternatively, improves efficiency without additional capacitance.
