Research ArticleOpen accessIn the abstractDesign of a Current Sensor for IDDQ Testing of CMOS ICMohd Liakot Ali, Nurul Huda KhamisThis study presents the design of an off-chip current sensor for IDDQ testing of CMOS (Complementary Metal-oxide Semiconductor) ICs (integrated circuit). It provides a linear voltage signal of IDDQ current with a conversion factor of 5 mV/μA without any amplification. A voltage-controlled switch is used to bypass the transient current peaks. It has also been shown that the sensor is … …American Journal of Applied Sciences, Vol. 2, Issue 3 · 31 Mar 2005 · 6,837 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Investigation into the Use of the Least Significant Bit Substitution Technique in Digital WatermarkingKevin Curran, Xuelong Xi, Roisin ClarkeDigital imaging companies lose revenue each year to people who are illegally copying and using their images. One prevention mechanism is to digitally encode images making it difficult for others to copy. This could be done using digital fingerprinting or simply adding a visible watermark. The information is hidden in a way that should not attract attention, but make it … …American Journal of Applied Sciences, Vol. 2, Issue 3 · 31 Mar 2005 · 7,471 accessesView PDFCite
