A fully integrated far-field powering system for RFID and implantable devices with monolithically fully integrated on-chip antenna in 0.18ÎŒm CMOS is presented. The chip receives power, clock and data wirelessly through RF signal at all the three ISM bands of 915 MHz, 2.45 GHz and 5.8 GHz. Measurements show a minimum input power of -19.41 dBm at 900MHz for chip operation, corresponding to 15.7 meter of operation range with an off-chip 0dB gain antenna. On the other hand, with its on-chip antenna at 5.8 GHz, the chip can be powered-up up to 7.5 cm distance. This is a huge improvement in terms of operation distance compared with other reported similar works with on-chip antenna as well as the off-chip antennas.
