i ABSTRACT Radiation hardening by design (RHBD) has become a necessary practice when creating circuits to operate within radiated environments. While employing RHBD techniques has tradeoffs between size, speed and power, novel designs help to minimize these penalties. Space radiation is the primary source of radiation errors in circuits and two types of single event effects, single event upsets...

This article presents a research work on the design and synthesis of sequential circuits and flip-flops that are available in digital arena; and describes a new synthesis design of reversible counter that is optimized in terms of quantum cost, delay and garbage outputs compared to the existing designs. We proposed a new model of reversible T flip-flop in designing reversible counter. Keywords—F...

Optical packet switching has received considerable attention over the last few years. In this paper we discus how optical signal processing can play a role in photonic packet routing. Two examples are given. Firstly we discuss ultrafast wavelength switching at 160 Gbit/s in a single semiconductor optical amplifier. Secondly, an integrated photonic flip-flop is discussed. Finally a discussion is...

A low power pulse triggered flip-flop with signal feed through scheme using Conditional Pulse Enhancement technique is presented in this paper. The proposed design adopts a modified True Single Phase Clock Latch structure and employs a signal feed through scheme to enhance the delay. The long discharging path problem in conventional explicit type pulse triggered flip flops are successfully solv...

The pertinent choice of flip-flop topologies is an essential importance in the design of VLSI integrated circuits for high speed and high performance CMOS circuits. Understanding the suitability of flipflops and selecting the best topology for a given application is an important issueto fulfill the need of the design to satisfy low power and high performance circuit. This paper presents a wides...

In this paper, we have modelled the flip-flop clock to output delay dependency on the data arrival time and introduced this phenomenon in timing analysis. Traditionally, finding the minimum clock period of a flip-flop based sequential design was based on the assumption that the setup-time and clock to output delay of a flip-flop are constant and hence each stage of the pipeline can be analyzed ...

This paper presents an efficient explicit pulsed static dual edge triggered flip flop with an improved performance. The proposed design overcomes the drawbacks of the dynamic logic family and uses explicit clock pulse generator approach to achieve dual edge triggering. The proposed flip-flop is compared with existing explicit pulsed dual edge triggered flip-flops. Based on the simulation result...
