HF RFID Tag Chip Impedance Measurements
This work provides the measurement data of sixteen high frequency (HF) radio frequency identification (RFID) transponder (tag) chips. In particular, the chip input impedance was characterized versus chip input voltage at 13.56 MHz. The measurement is based on the radio frequency current-voltage impedance measurement method and achieves, compared to previous work, higher measurement accuracy of lower than 1.5 %. The accompanying publication provides additional details.
The MATLAB data includes the measurements of impedance Z (including R and C of the chip parallel equivalent circuit) versus chip input voltage V_rms of up to five individual measurements of each chip (i.e., measurement series: 49, 50, 52, 53, 55).
