My thesis work involved the whole process of creating an OPA548 power amplifier. In the body of my thesis work, I started with a brief history, note on amplifier quality parameters, and description of the amplifier to be created. I then discussed extensively on the physical and chemical processes which I performed in the laboratory to create and assemble the PCB. The next stage was the testing and measurement of the amplifier parameters to ensure all parts work correctly. Finally, I compared the measured results and the simulated result.
