| Abstract: | A 13.56 MHz RFID chip is designed and fabricated in SMIC 0. 18 μm process technology. Test results show that the chip works well. A new structured AC - DC power generation block is introduced to replace the LDO structure to generate a stable power supply. A new structured demodulator is designed to compensate the uncertainty of process corners. Optimization is made on the system to simpli{y the TX circuits. The analog part power consumption is less than 100 μA. |
