Abstract:The proliferation of the IoT and low-power sensors would benefit greatly from battery-less compact radios that require no external components. Such a radio could be used for future RFID, wearable/implantable devices, and counter-counterfeit electronics. Previous demonstrations have focused primarily on miniaturizing the radio size, but relying on off-chip antennas. There is a big challenge to enable sufficiently small radios with on-chip antennas. The ultra-small die area precludes the use of any on-chip energy storage (such as large capacitors or inductors) or a large antenna, so sufficient power must be supplied wirelessly. The wireless power tone acts as a large blocker for the uplink communication signal, resulting in a poor uplink signal-to-noise ratio (SNR) and signal-to-blocker ratio (SBR). For wearable/implantable devices, the antennas are also the bottleneck of miniature designs. In this talk, I will demonstrate an RFID system used to detect counterfeit electronics that addresses the design challenge by a new two-tone technique. To miniaturize the wearable/implantable devices, I will talk about several ways to make use of the human body to get rid of the antennas.
