complementary metal-oxide semiconductor (cmos) technology has been the industry standard to implement very large scale integrated (vlsi) devices for the last two decades. due to the consequences of miniaturization of such devices (i.e. increasing switching speeds, increasing complexity and decreasing power consumption), it is essential to replace them with a new technology. quantum-dot cellular...

The latches are simple circuits with feedback from the digital electrical engineering. We have included in our work the C element of Muller, the RS latch, the clocked RS latch, the D latch and also circuits containing two interconnected latches: the edge triggered RS flip-flop, the D flip-flop, the JK flip-flop, the T flip-flop. The purpose of this study is to model with equations the previous ...

This paper provides the initial threshold to building of more complex system having reversible sequential circuits as a primitive component and which can execute more complicated operations using quantum computers. The reversible circuits form the basic building block of quantum computers as all quantum operations are reversible. The important reversible gates used for reversible logic synthesi...

Most digital systems textbooks treat the topic of converting one flip flop to another by simply giving the student certain simple conversion circuits, such as the use of an inverter between the R and S inputs of an RS flip flop to form a D flip flop, or tying together the inputs of a JK flip flop to make a T flip flop. However, a more general, but very simple, methodology for flip flop conversi...

In this paper, based on the coupled-mode and carrier rate equations, a dynamic model and numerical analysis of a multi quantum well (MQW) chirped distributed feedback semiconductor optical amplifier (DFB-SOA)  all-optical flip-flop is precisely derived. We have analyzed the effects of strains of QW and MQW and cross phase modulation (XPM) on the dynamic response, and rise and fall times of the ...

The proposed two types of multi-valued D flip-flops are NMAX-TG D flip-flop and NMIN-TG D flip-flop A NMAX-TG D flip-flop and a NMIN D flip-flop are composed of the components such as NMAX D flip-flops, NMIN D flip-flops and T-gate circuits.

This study presents the importance of reversible logic in designing of high performance and low power consumption digital circuits. In our research, the various forms of sequential reversible circuits such as D, T, SR and JK flip-flops are investigated based on carbon nanotube field-effect transistors. All reversible flip-flops are simulated in two voltages, 0.3 and 0.5 Volt. Our results show t...
