Design and Development of Computer Aided Device for Electroluminescence

Dr. Ajay Kumar Mishra

Abstract: The evolution of technology of computer-aided design, the synergistic combination of process, device and circuit simulation and modeling tools finds its roots in bipolar technology, starting in the late 1960s, and the challenges of junction isolated, double-and triple-diffused transistors. These devices and technology were the basis of the first integrated circuits, nonetheless, many of the scaling issues and underlying physical effects are integral to IC design, even after four decades of IC development. The computer aided design supplements the excellent designing and functionality of the parts list, specifications, drawing preparations and different other things important to the topic of research. A large number of fields and sectors make user of such designs such as architecture, electronics, naval science, aerospace and automotive engineering to a greater extent. The proposed work based on a device is called a computer aided device, consisting of with PIC (peripheral interface controller) microcontroller and optical sensor, which convert the phosphor light into voltage with respect to intensity of luminescence. The luminescence obtained from phosphor is dependent on the impurity concentration of the prepared phosphor and properties of zinc sulphide doped with copper and silver. Luminescence will also depend on applied voltage and frequency. When the frequency of EL cell is increases or decreases it affect the light of phosphor. The generated light is converted to equivalent electrical signal by optical sensor and it produces the voltage at the output. This output voltage is now applied at the input of the microcontroller. It converts the data in the digital form and process to further stages. The hardware implementation is carried out based on optical sensor and widely used PIC 16F873A micro controller based analog to digital converter and parallel port.
