In this paper, we propose a novel multiplexer-based full adder design, denoted as MUXFA, by using regular modules for arithmetic applications. The MUXFA full adder is composed of three identical modules, in which each module separately operates for XOR-XNOR function, sum function, and carry function. The structure of the multiplexer-based full adder can be easily constructed by merely a single ...

In this paper, a novel technique for multiplication is presented using Vedic multiplier. Vedic multiplier uses adders and hence making fast adder will increase the overall speed for multiplication. We have done comparative analysis for multiplication using different architectures of adder. For comparison we have taken Carry Select Adder (CSA), Square Root Carry Select Adder (SQRT-CSA). We have ...

In this paper we explore the test complexity of the adder function with respect to the robust path delay fault model. A lower bound of (n 2) for the cardi-nality of a complete test set for a combinational n-bit adder is proven. This result is valid for any adder design known until now. In addition we present a fast O(p n)-time adder that is fully robust path delay fault testable with a test set...

We consider the design of two well-known optimal timeadders: the “carry look-ahead” adder [6] and the “conditional sum”adder 1131.It is shown that 6 log,(n) 4 and 6 log2(n) + 2 test patterns suffice tocompletely test the n-bit carry look-ahead adder and the n-bit conditionalsum adder with respect to the single stuck-at fault model (for a given setof basic cells).

This paper mainly presents Mixed Gate Diffusion Input Full Adder based on static CMOS inverter topology. In this proposed mixed Full Adder topology, GDI Full adders are followed by inverters in the long Full Adder chain to improve the performances as compared to conventional single topology Full adder chain. For any circuits reducing the speed and power dissipation are the important constraints...

In this paper, we have designed a new variable latency adder and its implementation of decimation filter. There are multiple ways to implement a decimationfilter. 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...

In this paper we analyse a serial (ripple carry) and a parallel (Kogge-Stone) adder when operating in subthreshold at 100nm and 70nm. These are targeted for ultra low power consumption applications. The elementary gates used are threshold logic gates (perceptrons). Simulations have been performed both with and without considering the delay on the wires. These simulations confirm that wires play...

Digital adders form a significant part of the arithmetic unit in the processors. Many Digital Signal Processing (DSP) algorithms equally uses adder and multiplier element as its component to achieve the required arithmetic operation. Hence it is important to optimize the adder circuit in the gate-level itself to design it for the required standards. Recently there are various bio-inspired optim...

This paper presents a new design for 14 transistor single bit full adder, implemented using five transistor XNOR/XOR cell and transmission gate multiplexer. For transmission gate multiplexer complementary gate control signals are required and in 14 transistor full Adder both XOR and XNOR signals are generated. XNOR/XOR cell shows high power consumption than single XNOR gate. So, 8 transistor fu...
