Design of a LDO Circuit Based on RFID Technology

This paper introduces a design of LDO (low dropout regulator) circuit based on RFID (Radio frequency identification) technology. It consists of rectifier circuit, bandgap reference circuit and LDO circuit. The rectifier circuit receives and processes the signals sent by the antenna. The bandgap reference circuit generates a reference voltage. LDO circuit outputs a stable voltage. The circuit based on 0.18 μm CMOS process outputs a stable voltage of 1.8V.
