Quantum‐dot cellular automata (QCA) is a promising nanoelectronic technology having the characteristics of stable operation, breakneck speed, and ultralow energy consumption in theory. However, no scalable and modular architecture can facilitate circuit implementation, restricting the overall development of this technology. Different from the traditional programmable logic array (PLA) using AND‐OR arrays, this paper proposes a design method of PLA using crossbar structure in QCA. The PLA consists of multiple programmable units in which the majority gates can be programmed as AND/OR gates, and an inverter following each majority gate will invert the output as needed. To flexibly adjust the logic states of each programmable unit, a programmable clock scheme and N‐bit latch are then proposed. Therefore, a circuit can arbitrarily be achieved by programming the PLA. Four circuits, including full adder, 2–1 MUX, D flip‐flop, and 1‐bit memory, are designed, implemented, and simulated in QCA, by using this PLA. Experimental results show that the designed circuits realize logic functions correctly and stably.

Hypertension is one of the leading causes of cardiovascular disease morbidity in the world. If remains untreated, it may cause severe damage like heart attack or even death. Early detection is required to prevent the development of other cardiac abnormalities. Photoplethysmogram (PPG) is a bio signal that can be obtained optically by a sensor. It is studied to monitor the change of volume of blood and detect heart conditions. Previous studies have already applied PPG to detect hypertension at the software level. In this article, along with software-based detection, we have implemented a digital hardware-based system for detecting hypertension from signals recorded using PPG sensor. Xilinx ZedBoard Zynq-7000 field programmable gate array (FPGA) board is utilized for designing the embedded system. The hypertension detection accuracy is 98.02% at the software level while for the digital system, it is 96.05% consuming 0.374 W power. The study can be analyzed for other cardiac disease detection and medical equipment development.

Quantum dot cellular automata (QCA) technology is emerging as a future technology which designs the digital circuits at quantum levels. The technology has gained popularity in terms of designing digital circuits, which occupy very less area and less power dissipation in comparison to the present complementary metal oxide semiconductor (CMOS) technology. For designing the routers at quantum levels with non-blocking capabilities various multi-stage networks have been proposed. This manuscript presents the design of the NÂN Clos switch matrix as a multistage interconnecting network using quantum-dot cellular automata technology. The design of the Clos switch matrix presented in the article uses three input majority gates (MG). To design the 4 × 4 Clos switch matrix, a basic 2 × 2 switch architecture has been proposed as a basic module. The 2 × 2 switching matrix (SM) design presented in the manuscript utilizes three input majority gates. Also, the 2 × 2 SM has been proposed using five input majority gates. Two different approaches (1&2) have been presented for designing 2 × 2 SM using five input majority gates. The 2 × 2 SM design based on three input majority gate utilizes four zone clocking scheme to allow signal transmission. Although, the clocking scheme used in 2 × 2 SM using three input MG and in 2 × 2 SM approach 1 using five input MG is conventional. The 2 × 2 SM approach 2 design, utilizes the clocking scheme in which clocks can be applied by electric field generators easily and in turn the switch element becomes physically realizable. The simulation results conclude that the 2 × 2 SM is suitable for designing a 4 × 4 Clos network. A higher order of input-output switching matrix, supporting more number of users can utilize the proposed designs.
