In order to improve the accuracy of the digital to analog conversion (DAC), the reflection and crosstalk problems of the signal transmission process were studied in this paper. The Hyperlynx software was used for the simulation study of reflection and crosstalk problems of the master clock signal in the DAC circuit. Source end cascading termination resistor and remote end termination resistor a...

High dynamic range digital audio is the next frontier in audio reproduction. Achieving it means removing the many errors that typically compromise accuracy and thus the sense of realism that enthusiasts desire. High dynamic range starts with the power supply, then the digital-to-analog conversion, and continues right through to the speakers’ output. If the DAC is flawed then nothing that follow...

Analog-to-digital converters (ADCs) and digital-toanalog converters (DACs) play an important role in the design of data acquisition systems. ADCs are used to convert analog signals like the output from a temperature transducer, a radio receiver or a video camera into digital signals for processing. Conversely, DACs are used to convert digital signals back to analog signals. For example, the DAC...

A number of oversampling filters in association with a heavily oversampled and noise-shaped digital-to-analog converter (DAC) are presented for high-resolution applications in professional and consumer digital audio environments. Computer simulations of oversampling filter, noise shaper, and DAC errors are described, together with results to demonstrate interactive performance dependence on fil...

Abstract— A probe system has been developed on the basis of an external ADC/DAC module (ADC is analog-to-digital converter and DAC digital-to-analog converter). Using this system, it possible to determine all main plasma parameters continuous pulsed gas discharges. program for Windows operating in C++ control system. The can be used diagnostics devices included modern microplasma analyzers mixt...

This paper addresses the generation of spectrally pure sinewaves by combining the feedback structure of a Σ∆ loop with digital cancellation of unwanted spectral components in the output signal. In particular, the non-linearities of the in-loop Digital to Analog Converter (DAC) are compensated by applying a digital pre-distortion to the DAC input, and the feedback architecture is used to enhance...

By Zhihe Zhou, Ph.D. Washington State University August 2006 Chair: George S. La Rue We investigated the design and implementation of non-linear D/A converters (DAC) for a direct digital frequency synthesizer (DDFS), which consists of a phase accumulator, a phase-to-sine look-up table and a DAC. Using a non-linear DAC can significantly reduce the look-up table size, hence, reducing the power di...

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...

The principle of software radio architecture is investigated and applied for the implementation of a multi-standard terminal (MST) for operation with both current 2nd and future 3rd generation mobile radio systems. A key strategy for the design of the transceiver is to place the analog-to-digital converter (ADC) and digital-to-analog converter (DAC) as close as possible to the antenna. In addit...
