This paper presents low power clock gating adiabatic D flip-flop using single phase sinusoidal power clock scheme. We propose the clock gated single phase Quasi-Static Energy Recovery Logic (QSERL) D flip-flop at 90nm CMOS technology. In the previously proposed QSERL logic, two phase sinusoidal power clocks were used that increased the hardware complexity and clocking issues. In this paper, sin...

Abstract: In this paper we present a simple ultra low-voltage and high speed D flip-flop. The delay of the static differential flip-flop presented is less than 12% compared to conventional differential CMOS flip-flops. The presented circuits have been simulated using Hspice and are valid for 90nm TSMC CMOS process. The proposed high-speed and ultra low-voltage flip-flop can be used for any digi...

We give the probability that two vectors in d-dimensional Euclidean space m,n ∈ R which are separated in R by an angle θ ∈ [0, π/2] have angular separation θR > π/2 following random projection into a k-dimensional subspace of R, k < d. This probability, which we call the ‘flip probability’, has several interesting properties: It is polynomial of order k in θ; it is independent of the original d...

In this paper we present an ultra low-voltage and high speed D flip-flop. The flip-flop has an increased current level compared to standard CMOS circuits operating at low supply voltages. The increased current level is obtained by using a synchronized capacitive coupling to a semi floating-gate. The delay of the static differential flip-flop presented is less than 12% compared to conventional d...

Delay faults are frequently encountered in nanometer technologies. Therefore, it is critical to detect these faults during factory test. Testing for a delay fault requires the application of a pair of test vectors in an at-speed manner. To maximize the delay fault detection capability, it is desired that the vectors in this pair are independent. Independent vector pairs cannot always be applied...

We propose D-FLIP, a novel algorithm that dynamically displays a set of digital photos using different principles for organizing them. A variety of requirements for photo arrangements can be flexibly replaced or added through the interaction and the results are continuously and dynamically displayed. DFLIP uses an approach based on combinatorial optimization and emergent computation, where geom...

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...
