Resumen

In this work, RFID based sensors are introduced, which means very low-cost sensing nodes and loggers utilizing the hardware and protocols of traditional passive RFID transponders and readers for the short distance wireless sensor readout. Classic frequencies bands include LF ~125kHz, HF ~13.56MHz, and UHF ~900MHz. While HF and UHF off-the-shelf ICs and available IP exist to implement sensor transponders, is not the case of LF. In this work, an ASIC is presented to enhance the reading distance of a semi-active LF sensor transponder up to a few meters. The ASIC includes a 134.2kHz-centered band-pass amplifier, a ~50ms pulse detector, and a HV H-bridge to drive the antenna coil. It was fabricated in a 0.6μm HV-CMOS technology and tested. It was capable to detect the presence of a portable reader, up to a 5m distance, corresponding to an input signal as low as 40μVp in the antenna, with a continuous-time current consumption < 3μA.
