Research ArticleOpen accessIn the abstractA Novel Method for Testing Digital to Analog Converter in Static RangeK. Hariharan, S. Gouthamraj, B. Subramaniam et al.Problem statement: Linearity testing methods for DAC usually involves usage of non-linear analog components, which are indeed prone to various errors. Few other testing methodologies involve complex circuitry for measuring exactitude of DAC. Practically, it is difficult to build those as Built In Self Test (BIST) due to complexity of calculation, which demands more usage of ALU (or core of … …American Journal of Applied Sciences, Vol. 7, Issue 8 · 31 Aug 2010 · 7,458 accessesView PDFCite
