A new VLSI implementation for a finite field multiplier using reordered normal basis is presented. The hardware architecture uses domino logic building blocks as well as True Single Phase Clock (TSPC) flip-flops to achieve exceptional performance. The multiplier has been realized in a 0.18 μm CMOS process and can perform multiplication correctly up to a clock rate of 1.789 GHz, requiring 62048 μm2...
In this paper, we present a new method for the design of an n-bit synchronous binary up counter in quantum-dot cellular automata (QCA). This method is based on the JK flip-flop which almost always produces the simplest combinational logic in traditional sequential circuits. We implement a new QCA architecture for the JK flip-flop. Compared to the existing QCA JK flip-flop, the majority gate count,...
In a scan-based test architecture, the scan power and and test data volume can be reduced by utilizing a double tree scan (DTS) architecture. This paper presents a novel hardware implementation of the DTS architecture and compares the hardware overhead with the conventional scan architecture. The implementation proposed utilizes a clock structure which greatly decreases the number of clocked flip-flops...
With the event of nanoscale technologies, new physical phenomena and technological limitations are increasing the process variability and its impact on circuit yield and performances. Like combinatory cells, the sequential cells also suffer of variations, impacting their timing characteristics. Regarding the timing behaviors, setup and hold time violation probabilities are increasing. This article...
