Abstract:
In this project we attempt to design a simple ADC/DAC card which can be easily interfaced with 8085 microprocessor kit for Data Acquisition(DAQ) purposes. We extent our work by designing a pcb

APPLICATION:
Commerical ADC/DAC cards can cost hundreds of dollars, not viable for teaching purposes. This ADC/DAC card, which is much cheaper can be us ....etc

ABSTRACT
A pipelined analog-to-digital converter (ADC) architecture suitable for high-speed (150 MHz), Nyquist-rate A/D conversion is presented. At the input of the converter, two parallel track-and-hold circuits are used to separately drive the sub-ADC of a 2.8-b first pipeline stage and the input to two time-interleaved residue generation paths. Beyond the first pipeline stage, each residue path includes a cascade of two 1.5-b pipeline stages followed by a 4-b “backend” folding ADC. The full-scale re ....etc

DAC and ADC converters

-Data Converter impacts the factor for the performance of the overall radio design
-Requirements: very high sampling rates, high number of effective quantization bits, an operating bandwidth of several Ghz, a large spurious-free dynamic range, a reasonable price
-DAC and ADC converters
-Sampling and Quantization
-Nyquist Zones
-Aliasing
-Bandpass filtering – uses image to translate bandpass signals to baseband
-Errors occurs in Quantization
-Quantization Noise

Abstract
Synthetic Aperture Radar (SAR) image compression is important in image transmission and archiving. In this paper, SAR image compression using embedded zerotree wavelets algorithm, based on discrete wavelet transform (DWT), is researched. Aiming at special characteristics of SAR image such as speckle noise, the author added a denoise step in the flow of compression, trying to do some meaningful attempt in SAR image compression. Experiments carried out show that the improvement can reduce the speckle noise and improve the compu ....etc

i need to store real time values of an circuit output which varies from 5v to 24 v in a micro controller 8051 but my prob is as micro controller takes only digital values i need to use an ADC to convert but the limitation of ADC s 5v what can i do to capture the real time values. ....etc

MONOLITHIC LOW-POWER 16 B 1 SAMPLE/S SELF-CALIBRATING PIPELINE ADC

Abstract:- Pipelined architectures enable the implementation of high-speed, high-resolution, low-power analog-to-digital converters (ADCs). Concurrent processing of analog signals results in power and/or speed advantages over flash and multi step ADC architectures. While self-calibration techniques reduce the effects of component mismatches, the digital crosstalk due to correction circuitry can degrade the noise and linearity performance of the overall converter. Previous pip ....etc
