org, w.a.serdijn@tudelf Lnl Abstract-A multi-band autonomous wireless sensor node (AWSN) with temperature monitoring is designed in a standard 0.18 JLm CMOS technology. The AWSN comprises a high efficiency energy harvester, a power management module, a temperature-to-t ime converter (TTC) and a passive 402-MHz MICS band OOK transmitter for backscattering transmission. The AWSN demonstrates a sensitivity of -18.2 dBm at 13.56 MHz. The energy harvester achieves an RF-to-DC power conversion efficiency (PCE) of 11.5 %. From 0 to 100 DC, the temperature conversion and temperature accuracy of the TTC are 1.5 JLsf'C and 0.21 DC, respectively. The active area of the AWSN is 0.72 mm2• It consumes 1.5 JLW (RMS). |
