Abstract-Approximate computing is a promising approach for error-tolerant applications
running on the Internet-of-Things edge devices to reduce power consumption. However,
approximate computation is susceptible to side-channel attacks, such as attacks based
on differential power analysis (DPA). Energy efficiency could be further enhanced by
applying adiabatic logic in approximate edge computing while increasing its protection
against the side-channel attacks. As a case study, we are presenting two approximate
adders based on adiabatic logic to illustrate the benefits of approximate computation
combined with adiabatic logic. The proposed approximate adders leverage the dual-rail
property of adiabatic logic to minimize the overall size and further decrease energy
consumption. In this article, the first design is true sum approximate adder (TSAA),
whereas the second design is True Carry-out Approximate Adder (TCAA). There are fewer
transistors in adiabatic logic-based TSAA and TCAA compared to CMOS-based accurate
mirror adder (AMA). At 12.5-MHz operating frequency and 45-nm technology node, the
adiabatic TSAA and TCAA achieved power savings of 95.4% and 95.48% and energy
savings of 90.80% and 90.96% in comparison with the standard CMOS AMA. We also show
that both designs proposed are more secure against DPA attacks.

the edge of the network requires more energyefficient
and increased security solutions.1,2
Emerging strategies for designing low-power circuits
are adiabatic logic and approximate computing.
In approximate computing, accuracy is a
tradeoff to reduce the area. It is promising for
error-tolerant apps that run on IoT edge devices.
