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.

A Switching Logic Digitizer for Analog-to-Digital Conversion
IEEE Transactions on Applied Superconductivity, 2007The design and simulation of a complementary output switching logic (COSL) compatible, voltage state, switching logic comparator (SLC), and a flash analog-to-digital converter (ADC) for high-speed applications, with multigigahertz input bandwidth, is presented. A detailed design for the SLC is provided and verified with simulations.

An Oversampled Digital PWM Linearization Technique for Digital-to-Analog Conversion
IEEE Transactions on Circuits and Systems I: Regular Papers, 2004An algorithmic-based linearization process for uniformly sampled digital pulsewidth modulation (PWM) is described. It is shown that linearization of the intrinsic distortion resulting in uniformly sampled PWM can be achieved by using a fractional delay digital filter embedded within a noise shaping re-quantizer. A technique termed direct PWM mapping is

A GaAs CCD structure for multiplying digital-to-analog conversion
Proceedings of Canadian Conference on Electrical and Computer Engineering, 2002Multiplying Digital-to-Analog Converters (MDAC's) have been used in many electronic circuits that require digital programmable analog vector-matrix multiplications and flexible digital-to-analog interfaces. Design and simulation of a pipeline GaAs CCD MDAC are presented in this paper.

Direct Digital-to-Analog Conversion of Acoustic Signals
Bell System Technical Journal, 1980We report initial experiments on voice-band acoustic transducers (receivers) designed to accept digital (pcm) signals and directly convert the received bits into analog acoustic output. We describe experimental designs for 4, 5, and 6-bit digital receivers and for an acoustic system that functions as the desampling filter for the decoded signals.

Analog-to-digital and Digital-to-analog Conversion
1995Digital circuits, and computers in particular, are often used to interpret signals to provide some form of control action. This can include process control, e.g. where the thickness of a metal strip is to be controlled. The computer or digital circuit is supplied with measurements of thickness from a transducer that provides an output voltage ...

B70-3 Analog-to-Digital and Digital-to-Analog Conversion Techniques
IEEE Transactions on Computers, 1970During the sixties we witnessed the fulfillment of the semiconductor prophecies of the fifties. Semiconductor technology stimulated, and at the same time united, the worlds of computing, communications, and control. Today in all three areas we find many cases where signal processing and transmission can be performed most economically by digital means ...

A MAGNETIC REVERSIBLE COUNTER WITH DIGITAL TO ANALOG CONVERSION
1963Abstract : A time-shared, two-channel magnetic counter and digital-to-analog converter is described. The counter is capable of performing unit addition and subtraction. The design objective - to reduce the number of components - was well satisfied by the use of all-magnetic shift registers as the storage elements.

Signal sampling, analog to digital and digital to analog conversion
2004This chapter has laid the foundations for good sampling practice, in that it has shown why it is necessary to sample band-limited signals at a rate which is above than given rate. In a complementary manner, it has also identified why sampling at great speed is unnecessary, being wasteful of bandwidth and storage space, thereby adding nothing useful to ...
