This paper presents the design, the analysis and the complete characterization of a novel split-path Data Driven Dynamic (sp-D3L) full adder cell in IBM’s 65 nm CMOS process. The split path D3L design style derived from standard D3L allows the design of high speed dynamic circuits without the power overhead of the clock tree while providing significantly higher performance than the D3L due to r...

Arithmetic and memory address computation are performed using adder operations. Hence, design of adders form an important subset of electronic chip design functionality. Performance of BCD adders is to be considered with gate count, area, delay, power consumption. A new BCD adder design is attempted here to reduce the delay and thereby increasing the speed of response. BCD adder design is consi...

This filter design combination of CIC (cascaded-integrator-comb) filter and HB (half band) filter as the decimator filter to reduce the frequency sample rate conversion and detail of the implementation step to realize this design in h...

ÐThis paper presents a design methodology for high-speed Booth encoded parallel multiplier. For partial product generation, we propose a new modified Booth encoding (MBE) scheme to improve the performance of traditional MBE schemes. For final addition, a new algorithm is developed to construct multiple-level conditional-sum adder (MLCSMA). The proposed algorithm can optimize final adder accordi...

Reversible logic has extensive applications in quantum computing, it is a unconventional form of computing where the computational process is reversible, i.e., time-invertible. The main motivation behind the study of this technology is aimed at implementing reversible computing where they offer what is predicted to be the only potential way to improve the energy efficiency of computers beyond v...

The performance of existing adders varies widely in their speed and area requirements, which in turn sometimes makes designers pay a high cost in area especially when the delay requirements exceeds the fastest speed of a specific adder, no matter how small the difference is. To expand the design space and manage delay/area tradeoffs, we propose new adder architecture and a design methodology. T...

Superior electronic properties of graphene make it a substitute candidate for beyond-CMOSnanoelectronics in electronic devices such as the field-effect transistors (FETs), tunnel barriers, andquantum dots.

In this paper a new low power and high performance adder cell using a new design style called “Bridge” is proposed. The bridge design style enjoys a high degree of regularity, higher density than conventional CMOS design style as well as lower power consumption, by using some transistors, named bridge transistors. Simulation results illustrate the superiority of the resulting proposed adder aga...
