“…Ten input images are applied to the image blending application for different values of α ( α = 0.2, α = 0.5, α = 0.8). To produce these images, the approximate full adders have been used in the four less significant bits of the 8-bit adder (Zareei et al , 2021; Uoosefian et al , 2020; Safaei Mehrabani et al , 2017). It is worth noting that exact full adder cells are used in the higher significant half of the adder.…”

“…In the studies of Ataie et al (2019) and Zareei et al (2021), approximate adders based on the capacitive threshold logic (CTL) method have been presented. The CTL method can realize many complex Boolean functions with a simpler structure and fewer transistors compared to traditional implementation styles (Garcia et al , 2004).…”

“…A significant number of these devices perform complex computational functions such as multimedia processing, data mining and pattern recognition. Furthermore, they need to have an intelligent and sometimes real-time interaction with their environment and/or the user (Han and Orshansky, 2013;Rostami et al, 2020;Xu et al, 2016). To better do their tasks, these systems need to have more computing power.…”

Purpose Full adder cells are building blocks of arithmetic circuits and affect the performance of the entire digital system. The purpose of this study is to provide a low-power and high-performance full adder cell. Design/methodology/approach Approximate computing is a novel paradigm that is used to design low-power and high-performance circuits. In this paper, a novel 1-bit approximate full adder cell is presented using the combination of complementary metal-oxide-semiconductor, transmission gate and pass transistor logic styles. Findings Simulation results confirm the superiority of the proposed design in terms of power consumption and power–delay product (PDP) criteria compared to state-of-the-art circuits. Also, the proposed full adder cell is applied in an 8-bit ripple carry adder to accomplish image processing applications including image blending, motion detection and edge detection. The results confirm that the proposed cell has premier compromise and outperforms its counterparts. Originality/value The proposed cell consists of only 11 transistors and decreases the switching activity remarkably. Therefore, it is a low-power and low-PDP cell.

“…Among the nano technologies, the carbon nanotube field-effect transistor has been introduced as a successor for the replacement of MOSFET and comprises of two transistors known as p-type CNFET and n-type CNFET. In terms of the comparison of the MOSFET and CNFET, they have a higher switching speed, ballistic transport, same mobility of equal sizes, and more [19].…”

Adders are constituted as the fundamental blocks of arithmetic circuits and are considered important for computation devices. Approximate computing has become a popular and developing area, promising to provide energy-efficient circuits with low power and high performance. In this paper, 10T approximate adder (AA) and 13T approximate adder (AA) designs using carbon nanotube field-effect transistor (CNFET) technology are presented. The simulation for the proposed 10T approximate adder and 13T approximate adder designs were carried out using the HSPICE tool with 32 nm CNFET technology. The metrics, such as average power, power-delay product (PDP), energy delay product (EDP) and propagation delay, were carried out through the HSPICE tool and compared to the existing circuit designs. The supply voltage Vdd provided for the proposed circuit designs was 0.9 V. The results indicated that among the existing full adders and approximate adders found in the review of adders, the proposed circuits consumed less PDP and minimum power with more accuracy.
