The Attempt at a Solution

We have done much work in the class with problems on small signal and transistor biasing, we have not even talked about how to design such an amplifier above.Can someone recommend some good material describing amplifier design and how to meet these requirements? Our book only has problems, and I am not even sure where to start. The above criteria was the only given on the project, no number of BJTs or even a specific chip to use...

One of the best resources to start with would be the Linear Integrated Circuits textbook by D. Roy Choudhury. This book provides a detailed overview of amplifier design, including common circuit topologies, design constraints, and performance characteristics. Additionally, it provides step-by-step instructions for designing an amplifier to meet the specific requirements of a given problem. This book is highly recommended for anyone looking to learn more about amplifier design.

I would recommend starting by researching the basics of BJT amplifiers and their various configurations, such as common emitter, common collector, and common base. Once you have a good understanding of these configurations and their characteristics, you can begin to design a multistage amplifier that meets the given requirements.

Some key design considerations to keep in mind are the gain, input and output impedances, frequency response, and power consumption. You can use various circuit analysis techniques, such as small signal analysis and AC analysis, to determine the values of the components needed for each stage of the amplifier.

It may also be helpful to consider the trade-offs between different configurations and component values. For example, a higher gain may require more stages, but this may also increase the power consumption. Additionally, selecting the right transistor for each stage can greatly impact the performance of the amplifier.

In terms of resources, there are many textbooks and online resources available that cover BJT amplifier design in depth. I would recommend starting with a basic amplifier design tutorial and then moving on to more advanced materials as needed. It may also be helpful to consult with a professor or experienced engineer for guidance and feedback on your design. Good luck!
