摘要：
A 900-MHz RF (Radio Frequency) energy harvester implemented in TSMC 180-nm CMOS technology is presented. The RF energy harvester, which outputs an output voltage of 1.2V, incorporates a harvesting-efficiency tracking circuit to improve efficiency by changing the load of the rectifier automatically. By adopting dynamic comparator and duty-cycled operation a low power consumption is realized in the control circuit. For input RF power at -15dBm, the RF energy harvester achieves 30.1% efficiency.
