Summary: This article introduces a dead-band compensated multiband stacked electromagnetic energy harvester for powering sensor nodes. The harvester is adaptive to typical ambient radio frequency (RF) power levels found in the environment. It utilizes a stage-stage feedforward technique and a compensation circuit to enhance the output voltage, harvested power, and sensitivity. Experimental results show an improved efficiency by 13% on average under dead-band compensation, with the harvester achieving a start-up voltage of 320 mV at -24 dBm.

Summary: The reflection amplifier designed using 90-nm bulk CMOS technology for applications in the 60-GHz frequency band features a unique capacitive transmission line at the transistor source port that results in negative input resistance and return gain. The addition of an inductor at the drain port further enhances the return gain, with the fabricated die occupying a small 0.38 mm(2) area and consuming low dc power of 4.4 mW. The measured data show a peak gain of 8.4 dB at 57 GHz.
