I recently finished courses that covered op amps, capacitors, and inductors. I learned how to calculate the gain of an ideal op amp using nodal equations. I learned how to write transfer functions in circuits with capacitors and inductors by writing nodal equations in S-domain. I learned how to determine what type of filter the circuit is from the transfer function. I want to create an audio amplifier for mp3 player that will power a small speaker. I started simple and created a simple op amp. The circuit is attached. The circuit gets louder as R2 > R1 but there is a lot of distortion. The course I took at my university so far taught how to analyze a circuit and write equations, but I have no experience the other way around (i.e to design one). What would I need to do to make the output sound less distorted. I know I would probably need a capacitor or inductor somewhere but how do I know where to put it? And I'm guessing the next step would be to write a transfer function and solve for the component value?
