Photonic Digital to Analog conversion
2008 IEEE 25th Convention of Electrical and Electronics Engineers in Israel, 2008A digital-to-analog (DAC) converter based on an integrated optics multielectrode Mach-Zehnder interferometer (MZI) is presented and analyzed. The device described has superior performance regarding both linearity and dynamic range. The improvements are achieved by utilizing a special mapping method between the digital input sequence and the set of ...

The two most important architectures for constructing a digital-to-analog converter are the unary and binary approach. Both approaches have their merits. Next to the architecture, the second choice is the domain in which the converter is realized: voltage, current, charge or time.

18 bit digital to analog conversion
Proceedings of the May 5-7, 1970, spring joint computer conference on - AFIPS '70 (Spring), 1970In many control applications it is necessary to convert the digital output from a computer to a proportional voltage to effect control. Incremental changes in this analog voltage become relatively smaller as the number of significant digits is increased, until a point is reached where it is not possible to distinguish between voltages caused by the ...

On the performance of digital to analog conversion in the optical domain
2014 16th International Conference on Transparent Optical Networks (ICTON), 2014Optical domain digital to analog conversion (ODAC) has been proposed recently as a suitable technique able to cope with LED driving requirements and evolved modulation schemes (such as OFDM) in visible light communication systems (VLC). ODAC's concept is based on using groups of LEDs arranged in an array to transmit digital signals.

Digital to analog conversion in microelectronics
Sixth Symposium on Adaptive Processes, 1967This paper describes the design advantages and limitations of a hybrid digital-to-analog converter that is capable of a 12-bit resolution with an accuracy that is better than one-half the least significant bit. Through advances made in the research and applications of tantalum - nitride and nickel - chromium resistors, analog conversion systems can be ...

A new digital-to-analog conversion algorithm
1988., IEEE International Symposium on Circuits and Systems, 2003An algorithm is described which starts digital-to-analog conversion with the most significant bit. This algorithm can be realized by using only sample/hold circuits, and thus permits high-speed conversion. Error analysis shows that a conversion accuracy of 10 bits or higher is easily obtainable with a monolithic implementation. The architecture of data

Conversion Between Digital and Analog
1989The overall structure of a computer controller often fits the pattern shown in Fig. 8-1. The transducers and status sensors provide voltages to the analog channels of a multiplexer (MUX). The MUX selects one of these channels at a time and sends that signal on to the analog-to-digital converter (ADC), which feeds a binary number of perhaps eight bits ...

Modular multiplexed digital to analog conversion
Review of Scientific Instruments, 1980A design is provided for a 16 channel, multiplexed, digital to analog converter. Output channels are unipolar, zero to ten volts, with ten bit accuracy. Computer bus interfacing by means of a commercially available parallel interface results in a relatively low cost, easily assembled instrument to which digital to analog channels may be added as the ...
