This research presents the review of Analog to Digital Convertor (ADC). For ADC there are mainly four different methods, Flash ADC, Pipelined ADC, Successive Approximation ADC, and Sigma Delta ADC. The Flash ADC is the Fast ADC. For Designing the ADC, the parameters important are Static and Dynamic. In static parameters Differential Non Linearity Error (DNLE), Integral Non Linearity Error (INLE...

A new interleaved synchronous mirror delay (SMD) is proposed in order to reduce the circuit size. The conventional interleaved SMD has multiple pairs of forward delay array (FDA) and backward delay array (BDA) in order to reduce the clock skew. The proposed interleaved SMD requires one FDA and one BDA by changing the position of MUX. Simulation results show that about 30% power reduction and 40...

The motive of this work is to design on chip efficient low power techniques using VHDL coding. Serial links in network on chip provide many advantages in terms of crosstalk, skew, area cost, clock synchronization, and wiring difficulty when compared to multi-bit parallel data transmission. The proposed a novel coding technique reduces the number of transitions and hence reduces transmission ene...

The design of high speed circuits and optimization in function of technological and geometrical parameters are presented. MUX-driver design and optimization for 40 Gb/s ETDM transmission illustrate the proposed approach. The impact of collector thickness (WC) on driver performances is evaluated and assessed by circuit fabrication and measurements. 40 Gb/s electrical measurements of the realized...

Silicon-based optical media present several desirable properties for a wide range of applications. Herein, we propose novel hybrid integration scheme that combines silicon photonics platform and 5.5%--silica planar-lightwave circuit (PLC) platform. By exploiting the performance advantages each platform, fabricated polarization-insensitive low-crosstalk 8 switch butt-jointed with compact PLC-bas...

CSLA is used in many computational systems to alleviate the problem of carry propagation delay by independently generating multiple carries and then select a carry to generate the sum [1]. However, the CSLA is not area efficient because it uses multiple pairs of Ripple Carry Adders (RCA) to generate partial sum and carry by considering carry input Cin=0 and cin=1, then the final sum and carry a...

It is well known that there exists a tradeoff between the diversity gain and the multiplexing gain achievable by a particular MIMO coding scheme. In this report we first look at the optimal trade-off in the infinite signal-to-noise (SNR) regime of both Rayleigh independent and identically distributed (i.i.d.) channels and a more general MIMO channel model. We then look at the tradeoff of both S...

Reversible logic circuits have significant importance in bioinformatics, optical information processing, CMOS design etc. In this paper the authors propose the design of new RPLA using Feynman & MUX gate. VHDL base...

Monitoring changes on Earth's surface is a difficult task commonly performed using multi-spectral remote sensing. The increasing availability of remote sensing platforms providing data makes multi-source approaches promising, since it can increase temporal revisit rate. However, Digital image processing techniques are needed to integrate the data, since sensors can be quite different in terms o...
