This paper presents a background-calibration technique of timing skew for time-interleaved analog-to-digital converters (TIADCs). Without any kind of additional calibration signals, the timing skew between any two adjacent interleaved channels is detected by the capacitive charge pumps, and minimized by the digitally controlled delay elements (DCDEs). The calibration behaviors are analyzed and verified...
A new kind of multi-function electric power quality calibration system based on virtual instrument is proposed in this article. This system integrates virtual instrument programming and power electronics together, generating diverse signals of current electric power quality field all-in one. The proposed system integrated signal generator unit can achieve 1) the acquisition of high-speed digital data;...
