In this paper, we propse 16-bit sparse tree RSFQ adder (Rapid single flux quantam), kogge-stone adder, carry lookahead adder. In general N-bit adders like Ripple carry adder s(slow adders compare to other adders), and carry lookahead adders(area consuming adders) are used in earlier days. But now the most of industries are using parallel prefix adders because of their advantages compare to kogg...

A four port network adder-subtractor module, for surface plasmon polariton (SPP) waves based on a ring resonator filter is proposed. The functionality of module is achieved by the phase difference manipulation of guided SPPs through different arms connected to the ring resonator. The module is designed using the concepts of a basic two-port device proposed in this paper. It is shown that two po...

In this paper, a new low-voltage low-power CMOS 1-bit full adder circuit is proposed. The proposed full adder can provide a full voltage swing at a low supply voltage and offers superior performance in both power and speed than the conventional full adder, the transmission full adder, and the recent low-voltage full adder. Based on the simulation results performed by HSPICE, the new low-voltage...

Today’s technology demands compact, portable, fast, and energy-efficient devices. One approach to making devices is an in-memory computation that addresses the memory bottleneck issues of present computing system by utilizing a spintronic device viz. magnetic tunnel junction (MTJ). Further, area energy can be reduced through approximate computation. We circuit design based on logic-in-memory pa...

A carry-select adder can be implemented by using single ripple carry adder and an add-one circuit [1] instead of using dual ripple-carry adders. This paper proposes a new add-one circuit using the first zero finding circuit and multiplexers to reduce the area and power with no speed penalty. For bit length n = 64, this new carry-select adder requires 38 percent fewer transistors than the dual r...

A novel low power and low transistor count static energy recovery full adder (SERF) is presented in this paper. The power consumption and general characteristics of the SERF adder are then compared against three low power full adders; the transmission function adder (TFA), the dual value logic (DVL) adder and the fourteen transistor (14T) full adder. The proposed SERF adder design was proven to...

An all solid-state kicker modulator for the Dual-Axis Radiographic Hydrodynamic Test facility (DARHT-2) has been designed and tested. This kicker modulator uses multiple solid-state modules stacked in an inductive-adder configuration where the energy is switched into each section of the adder by a parallel array of MOSFETs. The modulator features very fast rise and fall times, pulse width agili...

Computing devices in pervasive environments have limitations on the following attributes: calculation capacity, power consumption, and chip size. The huge amount of operation required for applications of cryptographic primitives restricts the implementation of these primitives in pervasive environments. In order to overcome such limitations, we propose a new primitive for stream ciphers called ...

In this paper, a new four-moduli set {2n − 1, 2n, 2n+1 − 1, 2n+1 + 2n − 1} is proposed. The new moduli set choice because of a fast modulo 2n+1 + 2n − 1 adder has been proposed in literature. In order to work out the reverse converter for this moduli set, we introduce the technique for modulo 2n+1+2n−1 of a negative number and modulo 2n+1+2n−1 multiplication of a residue number by 2 and design ...
