A 0.23μW, 96 mV Input Voltage DC-DC Converter for Body Sensor Nodes
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 μW. The
operating temperature ranges from −40 °C to 100 °C

An 80mV Startup Voltage Fully Electrical DC-DC Converter for Flexible Thermoelectrical Generators
This paper presents a fully electrical dc–dc con-
verter designed for thermoelectric generator (TEG) for energy
harvesting applications. The proposed flexible TEG has been
achieved by a screen printing technology on a 80 μm thick com-
mon paper and thin Kapton foil and integrates 280 thermocouples
for an output voltage of about 75 mV with 5 K of thermal gradi-
ent. In order to step up the voltage at the output of the thin-film
flexible TEG, a dc–dc converter has been designed. This latter
operates with an input voltage ranging from 80 up to 370 mV. The
proposed dc–dc converter achieves an automatic control based on
pulsewidth modulation, ensuring 1 V output voltage. The control
circuit includes two sections. The first one provides a forward
control operating in the 80–150 mV input voltage range. The
second one operates a feedback control, as the output voltage of
TEG is higher than 150 mV. The dc–dc converter is implemented
in a 65 nm CMOS technology, achieving a 73% peak efficiency
