This special project presents a 10-Bit 1Gs/s 1.2V/3.3V Digital-to-Analog Converter using1 Poly 9 Metal SAED 90-nm CMOS Technology intended for mixed-signal and power IC applications. To achieve maximum performance with minimum area, the DAC has been implemented in 6+4 Segmentation. The simulation results show a static performance of ±0.56 LSB INL and ±0.79 LSB DNL with a total layout chip area ...

Steganalytic techniques are used to detect whether an image contains a hidden message. By analyzing different image features between stego-images (the image within which information is hidden) and cover-images (the Image in which information is to be hidden), a steganalytic system is able to detect stego-images. In this paper, we present a new method in LSB embedding by avoiding the change of s...

In the paper, for enhancing the security of the traditional LSB matching, two improved LSB-matching methods are proposed. In the steganograhical procedure, the Markov chain distance based on the second-order statistics is chosen as the security metric to control the modification directions of ±1 embedding. The first method is based on stochastic modification, which directly determines the modif...

I summarize some results from the recent CO survey of late-type, low surface brightness (LSB) spiral galaxies by Matthews et al. (2005). We have now detected CO emission from six late-type, LSB spirals, demonstrating that despite their typical low metallicities and low mean gas surface densities, some LSB galaxies contain a molecular medium that is traced by CO. We find that the CO-detected LSB...

A low-power 12-bit successive approximation register (SAR) analog-to-digital converter (ADC) with split-capacitor, nonbinary-weighted, and multiple-least-significant-bit (LSB)-redundant capacitor digital-to-analog converters (CDACs) is proposed. The proposed SAR ADC nonbinary-weighted multiple-LSB-redundant CDACs has an optimal mechanism for correcting the bit error decisions due to noise incom...

In modern stream cipher, there are many algorithms, such as ZUC, LTE encryption algorithm and LTE integrity algorithm, using bit-component sequences of p-ary m-sequences as the input of the algorithm. Therefore, analyzing their statistical property (For example, autocorrelation, linear complexity and 2-adic complexity) of bit-component sequences of p-ary m-sequences is becoming an important res...

The highest way to protect data from intruder and unauthorized persons has become a major issue. This matter led the development of many techniques for security, such as Steganography, Cryptography, Watermarking disguise data. paper proposes an image steganography method using Least Significant Bits (LSB) technique XOR operator secret key, through which key is transformed into one-dimensional b...
