Power circuit design & simulation using LT Spice

Abstract

Power Amplification is a commonly used process in speakers, headphones and many other electronic applications. This involves increasing and decreasing the magnitude of voltage, current and power of an input signal, which in our modern world, is used in power amplifiers. The project focuses on the research on power amplifier applications and performances through the use of hardware and software. In this report, the main topics that will be covered consists of three portions which are the experiments and testing results, comparison of hardware and software simulation results and optimization. The experiment and results section shows the evaluation of performances of the AD818 & PA119 operational amplifiers (OP-AMP). As for the comparison of hardware and software, it will highlight the waveform and results attained during the project. In addition, the hardware and software simulated results must resemble each other with minimum variance. Last but not least, the optimization sections will show the key improvement required to enhance the performances of the existing circuits.
