Abstract:
This paper proposes a method for RF-to –
DC energy harvesting with high efficiency using
TFET, sensitive low load resistance and increased
dynamic range for low power devices. It measures
peak power conversion for more power efficiency at
low input power. The Proposed TFET rectifier takes
the advantages of a forward bias technique to control
the selective transistor to rectify the conduction. The
tunnel devices are used for specific characteristics to
increase the strength of weak input signals. In this
paper it is proposed to have a design performance
related with peak power conversion efficiency for
power and amplitude, our design fabricated starts to
operate -18dBm input. The operation of rectifier
circuit with tested frequency GSM 900 band includes
other frequency band such as 2.4 GHz with normal
impedance matching. The efficiency of the measured
peak power conversion for the implemented TFET is
87% and -19.2dBm (13μW) sensitivity and this is the
best rectifier utilization for energy harvesting
applications and Internet of things.
