چکیده
Introduction A common use of high-resolution digital-to-analog converters (DACs) is providing controllable precision voltages. Applications for DACs with resolution up to 20 bits, precision up to 1 ppm, and reasonable speed include gradient coil control in medical MRI systems; precision dc sources in test and measurement; precision set-point and position control in mass spectrometry and gas chromatography; and beamprobing in scientific applications.

A 20-Bit (1 ppm) Linear Slope-Integrating A/D Converter
By combining an ‘‘inferior’’, 20 year old A/D conversion technique with a microprocessor, a developmental A/D converter achieves 1 part-per-million (20-bit) linearity. The absolute accuracy of the converter is primarily limited by the voltage reference available. The precision achieved by the unlikely combination of technologies surpasses conventional approaches by more than an order of magnitu...

A 10-bit 140MS/s digital-to-analog converter (DAC) with improved current mirror is presented. In order to improve the resolusion of a 10-bit DAC, a segmented decoding plus R-2R architecture will be introduced. DAC system modeling shows that the dynamic performance of the DAC is strongly dependent on the output impedance of DAC current source. The gain-boosting technique is applied to increase t...

The resulting equations require only the addition and multiplication processes; therefore, it can be implemented efficiently on a microprocessor. An extensive angle error analysis...
متن کاملA High Precision and Low Power Digital Synchronous Clock for Sensor Network
The applications envisioned for sensor networks require collaborative execution of a distributed task amongst a large set of sensor nodes. This is realized by exchanging messages that are time-stamped using the local clocks on the nodes. Therefore, time synchronization becomes an indispensable piece of infrastructure in such systems. We propose a design of synchronous clock using digital tune m...
