Abstract

Energy harvesting from ambient sources can be used to supply low-power devices in remote areas or where it is costly to replace batteries. Other than light, temperature gradients, vibrations and radio frequency electromagnetic radiation, it is also possible to harness ambient energy from an alternating electric or magnetic field. Magnetic field energy harvesting (MFEH) is possible with inductors near AC current-carrying power lines. This paper presents a novel converter for boosting the low-voltage AC output of small magnetic field energy harvesters to power standard electronic circuits. The design in a 180 nm CMOS process is illustrated and efficiency and system level power measurements are performed to proof the concept.
