An RF energy scavenging circuit implementing a power matched Villard voltage doubler followed by a switched capacitor DC-DC converter for scavenging ultra-low RF power levels (20 dBm) is presented. Measurement results for the circuit, fabricated in a 130 nm CMOS process, show that 1 V can be generated across a 5 M load from as little as 25.5 Bm of input RF energy at 2.2 GHz. This represents a 9.5 dB improvement, over the measured sensitivity of our RF energy scavenging circuit without the use of a switched capacitor DC-DC converter stage.
