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...

The jitter, obtained by SFEMG recordings, mainly reflects the neuromuscular transmission time variability and is usually Gaussian distributed. Here is reported the bimodal distribution of the interpotential intervals, the flip-flop phenomenon. Long flip-flop in cases of reinnervation may indicate alternatively continuous and saltatory nerve conduction. Short flip-flop in normal subjects may be ...

An all-optical flip-flop, the memory of which is based on dispersive bistability in a single vertical cavity semiconductor optical amplifier, is demonstrated experimentally. Flip-flop control is achieved using two mechanisms: cross-phase modulation to set the flip-flop and cross-gain modulation of the holding beam within a remote SOA to reset it. Optical control signals are sub-milliwatt in pow...

Some active stars show a so-called flip-flop phenomenon in which the main spot activity periodically switches between two active longitudes that are 180◦ apart. In this paper we study the flip-flop phenomenon by converting results from dynamo calculations into long-term synthetic photometric observations, which are then compared to the real stellar observations. We show that similar activity pa...

An all optical set-reset flip flop is presented that is based on two coupled identical laser diodes. The lasers are coupled so that when one of the lasers lases it quenches lasing in the other laser. The state of the flip flop is determined by which laser is currently lasing. Rate equations are used to model the flip flop and obtain steady state characteristics. The flip flop is experimentally ...

Efficient power management in wireless sensor network is a critical issue as the sensor nodes are low powered devices. In a sensor node, flip flop consumes large amount of power as they make maximum number of internal transitions. Reduction in the power consumed by flip-flops shows a deep impact on the total power consumed. Hence, designing low power flip flop cells are highly important for enh...

In this paper, a preprocessing circuit for ISFETs (Ion-sensitive field-effect transistors) to measure hydrogen-ion concentration in electrolyte is presented. A modified flip-flop is the main part of the circuit. The modification consists in replacing the standard transistors by ISFETs and periodically switching the supply voltage on and off. Concentration of hydrogen ions to be measured discont...

The choice of flip-flop technologies is an essential importance in design of VLSI integrated circuits for high speed and high performance CMOS circuits. The main objective of this project is to design a Low-Power Pulse-Triggered flip-flop. Flip-flops are the major storage elements in all SOC’s of digital design. They accommodate most of the power that has been applied to the chip. Flip-flop is ...

Providing resistance against side channel attacks especially differential power analysis (DPA) attacks, which aim at disclosing the secret key of cryptographic algorithm is one of the biggest challenges of designers of cryptographic devices. In this paper design of novel data flip-flop compatible with three-phase dual-rail logic (TDPL), called Charge recycling TDPL flip-flop is investigated. Th...
