Some of you might already know me from previous posts, in which I was trying to create circuits like amplifiers without knowing anything about analog circuit design.

I'm an Electrical & Computer Engineer student and I've completed all the basic subjects about circuit analysis (DC, AC, and nonlinear electronics like diodes, MOSFETs, and BJTs). Currently, I'm following the path of energy and power circuits like transmission lines, but I want to learn electronics (small power analog circuits and later digital as well) for my hobby.

Give me any circuit with known components and sources, and I can calculate all the voltages and currents across the circuit (as long as it does not result in a very big system where I can be lost in calculations).

I also have a deep understanding of how these components work individually and the mathematical models describing them.

And yet I can't design anything! I have no idea where to start, how to think when designing something, how to connect components in the order they must be connected in order to create the desired circuit, or how to choose the values of these components (resistance, capacitance, inductance).

Is there a good book, video tutorials, or a step-by-step website guide that teaches you all the stuff that you need to know when trying to build a circuit? I don't want textbooks that explain Kirchhoff's laws, Thenevin's and Norton's theorems, apparent power, Fourier transform/analysis, steady state analysis, Laplace, etc. I already know that.

People have told me that circuit design is a subject of its own and needs to be learned separately from circuit analysis.

But I can't find anything on the internet. All of them are showing you a circuit, give you the components and let you just build it. I want to know how to make it work from scratch on my own, not copy-paste the work of someone else.

I'm currently reading a book called "Practical Electronics for Inventors" but I got bored. It just explains how circuits like filters work and not how to design them yourself. Maybe I'm judging it too quickly. But it also shows a lot of math that I already know.

Do you have any suggestions?
