Abstract
A scheme for a wirelessly-powered passive sensor is presented in which the extra received power beyond the sensitivity level is stored and later used to enhance the sensitivity of the wireless sensor. A prototype chip has been designed and fabricated in a 0.13µm CMOS technology. The measurement results show that the aforementioned energy storage mechanism improves the sensitivity of the wireless sensor from −19.5dBm to −29dBm at 900MHz and from −15.4dBm to −26.5dBm at 2.4GHz.
