Abstract

In this paper, a time-domain measurement of quality factor is described. Based on the time-domain measurement principle, we have proposed an integrated architecture. The experimental results performed on a printed circuit board prototype show a measurement accuracy of 0.1%, which is the best theoretical attainable accuracy in our case and only limited by the fundamental quantization error. The circuit design, the performance analysis, and the experimental setup are discussed in this paper.
