Abstract:
We present a fully-integrated compact (1.1 mm2) target device for Near Field Communication (NFC). The design of the key analog part of the tag IC is presented, which includes a robust demodulator for 10% ASK envelope detection, a high-quality random number generator, an adaptive RF limiter, and a low power clock generator. A 128 bit advanced encryption standard (AES) with new cyclic key generation is used for secure data encryption and decryption. An on-chip 4Kb EEPROM is used to support the AES operation. The tag chip is fabricated in a 1-poly 6-metal low-power (LP) 0.18 μm CMOS process with a CoSi2-Schottky diode and EEPROM process.
