HIGH-PERFORMANCE TWO-PHASE SINE WAVE GENERATOR FOR IMPEDANCE BRIDGES
Abstract
The paper describes the experimental study of a two-phase sine wave generator intended for use in an impedance metrology. It is based on a 20-bit digital-to-analog converter (DAC) based on the R-2R architecture. Some tests for evaluation of the generator were carried out. The excellent parameters of the DAC made possible achieve a very good stability of the complex voltage ratio which is about ± 0.25 part in 10<sup>6</sup> for the amplitude ratio and less than ± 0.25 µrad for the phase difference.
