Abstract
An integrated circuit is disclosed. The integrated circuit includes a UHF RFID tag physical layer that rectifies a UHF RFID signal acquired through a first antenna using a first rectifier to generate a first DC voltage, an NFC tag physical layer that rectifies an NFC signal acquired through a second antenna to generate a second DC voltage, a microcontroller unit, a non-volatile memory that stores data processed and data to be processed by the UHF RFID tag physical layer, and data processed and data to be processed by the NFC tag physical layer under control of the microcontroller unit, and a detector that detects a voltage input of one of the first DC voltage and the second DC voltage, and supplies the detected DC voltage to one of the UHF RFID tag physical layer and the NFC tag physical layer, the microcontroller unit, and the non-volatile memory.
