As shown in Fig. 1, a detailed design of the audio amplifier.
1- Simulate the circuit on any preferred simulation tool of your choice (SPICE, Proteus). You can use an AC-source as the input signal, and you can also use a regular resistive load as a speaker.
- Perform DC-Analysis to calculate all currents and voltages for all circuit elements.
- Perform AC-Analysis to calculate the amplifier's voltage gain.
This project aims to use the studied devices throughout the semester to develop a very popular circuit, the "audio amplifier." The goal of this project is to ensure that you can fully understand the concepts of BJT amplifiers and how they work, different BJT amplifier topologies, and the usage of each. The project involves the input sound signal and the speaker.
