Power dissipation has become an overriding concern for VLSI circuits and it may come to dominate the total chip power consumption as the technology feature size shrinks. The main aim of this paper is to minimize the leakage power by using a ultra low leakage techniques. In this work we are choosing the Benchmark circuit as full subtractor . This full subtractor are designed by using different t...

This study presents efficient algorithms for performing multiply-by-3 (3N) and divide-by-3 (N/3) operations with the additions and subtractions, respectively. No multiplications and divisions are needed. Full adder (FA) and full subtractor (FS) can be implemented to realize the N3 and N/3 operations, respectively. For fast hardware implementation, this paper introduces two basic cells UCA and U...

In recent years, Quantum Electronics and Reversible Logic have emerged as a major area of research having applications in low power CMOS circuits, cryptography, optical computing and nanotechnology. The fact that classical logic gates such as AND, OR, XOR etc., barring the NOT gate, cannot predict the input given the output and hence generate heat due to information loss, has given rise to the ...

One of the most important tasks in design and manufacturing of integrated circuits is the testing phase. Distinguishing between faulty and fault free ICs is a difficult task Therefore, simulations are being done for different circuits to identify fault free and faulty circuits. The circuits include analog circuits, digital circuits &mixed signal circuits. Analog circuits like Low pass filter, H...
