چکیده

A logic style known as Phased Logic(PL) is applied to arithmetic circuits. Phased logic is a dual-rail LEDR logic style that allows automatic translation from a clocked netlist to a self-timed implementation. Bit level dataflow, early evaluation and automatic filtering of transient computations within PL circuits can lead to both increased performance and higher energy efficiency than the original clocked netlist. performance decrease but is 2X more energy efficient than the clocked counterpart.

A High-Speed Dual-Bit Parallel Adder based on Carbon Nanotube ‎FET technology for use in arithmetic units

In this paper, a Dual-Bit Parallel Adder (DBPA) based on minority function using Carbon-Nanotube Field-Effect Transistor (CNFET) is proposed. The possibility of having several threshold voltage (Vt) levels by CNFETs leading to wide use of them in designing of digital circuits. The main goal of designing proposed DBPA is to reduce critical path delay in adder circuits. The proposed design positi...

Optimization of NULL convention self-timed circuits

Self-timed logic design methods are developed using Threshold Combinational Reduction (TCR) within the NULL Convention Logic (NCL) paradigm. NCL logic functions are realized using 27 distinct transistor networks implementing the set of all functions of four or fewer variables, thus facilitating a variety of gatelevel optimizations. TCR optimizations are formalized for NCL and then assessed by c...

Verification of arithmetic datapath designs using word-level approach - A case study

The paper describes an efficient method to prove equivalence between two integer arithmetic datapath designs specified at the register transfer level. The method is illustrated with an industrial ALU design. As reported in literature, solving it using a commercial equivalence checking tool required casesplitting, which limits its applicability to larger designs. We show how such a task can be s...

A Novel Domino Logic for Arithmetic Circuits

This paper presents a low power and high speed ripple carry adder circuit design using a new CMOS domino logic family called feedthrough logic. Dynamic logic circuits are important as it provides better speed and has lesser transistor requirement when compared to static CMOS logic circuits. The proposed circuit has very low dynamic power consumption and lesser delay compared to the recently pro...
