This paper presents an ultra-low power DC-DC converter to be embedded into body sensor nodes. The proposed DC-DC converter is used to step-up the voltage at the output of a micro-thermoelectric generator up to a usable supply voltage between 0.42 and 1.05 V. Measurements have been conducted on ten available samples. The resulting mean value of the minimum input voltage is 96 mV. At the minimum input voltage, the power consumption is only 0.23 $mu ext{W}$. The operating temperature ranges from -40 °C to 100 °C.

Abstract
This paper presents an ultra-low power DC-DC converter to be embedded into body sensor nodes. The proposed DC-DC converter is used to step-up the voltage at the output of a micro-thermoelectric generator up to a usable supply voltage between 0.42 and 1.05 V. Measurements have been conducted on ten available samples. The resulting mean value of the minimum input voltage is 96 mV. At the minimum input voltage, the power consumption is only 0.23 $mu ext{W}$. The operating temperature ranges from -40 °C to 100 °C.
