— In this paper, a novel quantum-dot cellular automata (QCA) adder design is presented that reduces the number of QCA cells compared to previously reported designs. The proposed one-bit QCA adder structure is based on a new algorithm that requires only three majority gates and two inverters for the QCA addition. By connecting n one-bit QCA adders, we can… (More)
In this paper, we introduce a novel reconfigurable graphene logic based on graphene p-n junctions. In this logic device, switching is accomplished by using co-planar split gates that modulate the properties that are unique to graphene, including ambipolar conduction, electrostatic doping, and angular dependent carrier reflection. In addition, the use of… (More)
This paper introduces the image reconstruction algorithm from Sheffield group and the validity of this algorithm to the Sussex MK4.
The Sussex MK4 electrical impedance mammography (EIM) is an EIT system dedicated to breast cancer detection. The novel electrode configuration with its data acquisition method has significantly enhances the system performance by improving the signal-to-noise ratio (SNR).
In this paper, novel reconfigurable architectures are introduced to utilize high-density resistive memory (RRAM) to build FPGA components. Different from the existing CMOS-nano hybrid circuits that use crossbars, the proposed rFPGA structures consist of mainly 1T1R structures (1 CMOS transistor is integrated with a two-terminal resistive nanojunction) that… (More)
—In this paper, we introduce a novel reconfigurable architecture, named 3-D field-programmable gate array (3-D nFPGA), which utilizes 3-D integration techniques and new nanoscale materials synergistically. The proposed architecture is based on CMOS nanohybrid techniques that incorporate nanoma-terials such as carbon nanotube bundles and nanowire crossbars… (More)
With technology migration into nano and molecular scales several hybrid CMOS/nano logic and memory architectures have been proposed thus far that aim to achieve high device density with low power consumption. The discovery of the memristor has further enabled the realization of denser nanoscale logic and memory systems. This work describes the design of… (More)
