This paper presents results of analyses of full adders structures to build of low-power adders for specific data. At first four 1-bit full adder cells were selected from literature, designed in UMC 180nm technology and simulated for assessment of theirs energetic and time parameters. Extended power consumption model, taking into consideration input vector changes, was used, giving more accurate values...
This paper presents an implementation of a digital image processing application on the field programmable gate array (FPGA) using the residue number system (RNS). This application includes applying a number of filters in spatial domain, such as sharpen, edge detection and enhancing on a gray-scale image. All the processing is done using the RNS instead of the binary number system. The proposed work...
A novel RTL countermeasure intended to protect the AddRoundKey step of the AES algorithm against DPA or CPA attacks has been proposed and tested on an AES encoding coprocessor implemented on FPGA. Experimental results based on CPA attacks confirmed the effectiveness of the proposed countermeasure, showing that with 100000 acquired power curves, the absolute value of correlation function is one order...
The design and measurements results of analog-to-digital converter implemented in CMOS 180 nm technology have been presented in this paper. The successive approximation architecture with charge redistribution has been chosen. Much emphasis was placed on limiting the area occupancy of the whole chip so as its power consumption, which makes the described circuit suitable for multichannel applications...
This paper presents a dual stage charge-sensitive amplifier designed for long silicon strip detectors. It allows to obtain a linear Time-over-Threshold processing using constant current feedback for charge and interaction time measurements when working with large capacitance sensors (e.g. Cdet=30 pF). The paper includes details of architecture and simulation results.
The paper presents an optimized architecture of cascaded integrator-comb (CIC) digital filter structure. The structure is suitable for implementation in application specific integration circuits (ASICs) or field programmable gate arrays (FPGAs). The main advantages of the architecture are higher working frequency, smaller area size and lower power consumption. Software in C++ language was written...
Delay-based Dual-rail Pre-charge Logic (DDPL) is a logic style introduced with the aim of hiding power consumption in cryptographic circuits when a Power Analysis (PA) attack is mounted. Its particular data encoding allows to make the adsorbed current constant for each data input combination, irrespective of capacitive load conditions. The purpose is breaking the link between dynamic power and data...
What decoder is, everyone knows. The paper presents a method of n-to-2n-lines decoders design in easy way. Based on a few building blocks only, especially prepared, and appropriate procedure of their placement, a decoder of any size can be build. Layouts of all needed fundamental blocks were designed in CMOS technology, as standard library Moreover, some important parameters, such area, power dissipation...
