Abstract
This paper includes a basic review, analysis, and interesting insights, oriented to designers when power consumption is a critical constraint, of Stand-Alone Data Converters. These data converters are an indispensable part of the analog design technique and the only bridge to establish an adequate communication link between analog and digital devices. In fact, this article is dedicated to showing the principal types of the analog-to-digital converters (ADC) and digital-to-analog converters (DAC) families of data converters popular in modern analog design techniques. In fact, these data converters are also cost-effective devices because of the huge number of existing and newly developed solutions with their significant practical features providing more relevant applications in specific type of ADC or DAC process. The overview of data conversion, ADC and DAC data converters, communication bus to Micro Controller Units (MCU), and benefits of data conversion are described.
Highlights
Today, many electronic applications or embedded systems include a combination of digital and analog circuits in which the digital part is used to receive information from an analog circuit and vice versa to form an analog signal out of digital information
The main characteristics of an analog-to-digital converters (ADC) for selection criteria are following: the bandwidth, the signal to noise ratio and the dynamic range
The Total Harmonic Distortion (THD) is a measurement of the distortion and noise, which are introduced to the signal by the digital-to-analog converters (DAC)
Summary
Many electronic applications or embedded systems include a combination of digital and analog circuits in which the digital part is used to receive information (signal) from an analog circuit and vice versa to form an analog signal out of digital information. The ADC solutions are widely used in modern electronics to represent values of analog signals in digital form for subsequent storage or logic processing by traditional micro-controllers. Is proposed an approach to ADC and DAC conversion with memorable devices in which the digital value of the signal is written into the states of storage systems. This approach is directly compatible with the memorable logic architectures recently proposed, and can be used in chips interfacing the usual electronic components. The output waveforms from power electronic devices like rectifiers are periodic but not sinusoidal, so the equations available for pure sinusoidal waveforms cannot be applied in power electronics [1], [3 - 5]
