A Review of Implementing ADC in RFID Sensor

Figure 1

Maximum allowed magnetic field strength for 13.56 MHz ISM band according to European and American regulations (60 dBA/m @ 10 m and 42 dBA/m @ 10 m, resp.). The lower curve represents the magnetic field strength of a typical HF reader (square coil, 10 × 10 cm, 6 turns, 125 mA).
