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 ...

In this paper we propose, experimentally realize and study possible applications of a new type of logic element: random flip-flop. By definition it operates similarly to a conventional flipflop except that it functions with probability of 1/2 otherwise it does nothing. We demonstrate one practical realization of the random flip-flop based on optical quantum random number generator and discuss p...

Timing Optimization is one of the most important objectives of the designer in the Modern VLSI world. Memory elements play a vital role in Digital World. The basic memory elements of designer considerations are Latch and flip flop. In this paper, we analyze the design of Single-bit Flip flop (SBFF) and made performance comparison over the Multi-bit Flip-flop (MBFF). For improving Flip flop perf...

In this paper, a high-speed double-edge-triggered flip-flop designed in 0.18μm CMOS technology is presented. Flip-flops, to a large extend, determine the speed of synchronous systems. The proposed flip-flop can operate with a clock rate as high as 12.5GHz, which translates to 25GB/s data rate. It samples the data on both edges of the clock. All signals are realized differentially. The different...

The paper proposed a new design for implementing semi-static flip-flop for low power and high performance applications. In this work, comparative analysis of six existing flip-flop designs along with the proposed design is made. The proposed design has better power, delay and PDP than the existing architectures. All simulations are performed on TSpice using BSIM models in 130 nm process node. T...

In this paper, the proposed flip-flop reduces power consumption by reducing the clock switching power that was wasted otherwise. Unlike many other gated flip-flops, the proposed gated flip-flop has state retention property to save power and to switch circuit between idle and active modes smoothly. The feedback path is also improved in the proposed flip-flop to decrease power dissipation. The pr...

The authors introduce two low-cost, modular, totally self checking (TSC), edge triggered and error propagating (code disjoint) flip-flops: one, a D flip-flop used in TSC and strongly fault secure (SFS) synchronous circuits with two-rail codes, the other a T flip-flop, used in a similar way as the D flip-flop but retaining the error as an indicator until the next presetting, to aid error propaga...
