An Analysis Of An Audio Amplifier Utilizing An Operational Amplifier And Negative Feedback, Anthony Francis Lexa
Masters Theses
"An audio amplifier utilizing a monolithic operational amplifier is analyzed. The analysis is a block diagram approach where the amplifier is divided into three parts; operational amplifier, power amplifier, and feedback network. A Fourier series analysis is used to describe the distortion and signal components of the amplifier output. The results of this analysis demonstrate the advantage of large negative feedback on frequency response and harmonic distortion. Using relatively few passive components a high quality audio amplifier is constructed with an output power of 15 watts RMS power and negligible harmonic distortion"--Abstract, page ii.
