Abstract | This paper proposes a 2.4-GHz pre-bias RF energy harvesting rectifier with-35-dBm sensitivity for self-powered chips of wireless sensor networks (WSNs) for Internet of Things (IoT) applications. For high sensitivity, a pre-bias topology is presented by designing pre-stage and drive-stage rectifiers separately with multiple antennas. The pre-stage and the bias circuit just provide a proper bias voltage without driving loads. At single drive-stage configuration -35-dBm sensitivity can be achieved with 2.4-GHz RF input power, 10-M Omega output load and 0.5-V continuous output voltage. When an 1% duty-cycled operating mode is adopted, 25-mu W power can be supplied intermittently with 0.5-V output voltage. This proposed circuit is designed in 0.18-mu m standard CMOS process. |
