Abstract We in this work, have created a design of instrumentation amplifier circuit using three voltage feedback amplifiers. The transfer functions with operation principles are available using equations with important static and dynamic parameters. With the help of the design procedures and recommendations for simulation models we have first developed a formulae and recommendations for simulation modelling. The proposed design is... Read More

Abstract The functioning of the ionizing radiation detector circuits and their operations are tested using simulations in the current work. We have verified the semiconductor optoelectronic detectors of ionizing radiation. Based on the outcome we proposed circuits for temperature compensation in the optoelectronic detectors performance with low energy levels. This environment has the ionizing particles in fast and slow changes. We... Read More


Noise Reduction in Controlled Environment using Simulation

Abstract Noise reduction with rotating elements in controlled environment is being studied in our work. To support our work, we have presented the results of simulation application. The results were obtained using the Active Noise Control modules. Initially we have explained the basic system of ANC and further described the results with analysis.... Read More
