Welcome to my burrow, dear visitor. On this site I try to provide you with a few commented links to the best resources for learning analog electronics and related topics like math. The quickest way to get an idea what you can find on this site is to take a look at the Overview page. Or you can continue to read this page here and get a more detailed explanation of the different topics that are covered. You might also take at look at the Top 10 page, where I have listed the resources that I consider to be the most interesting ones. And you can find the latest additions by looking at the what's new page.

If you want to learn about analog electronics, the first thing you should do is to join a community of other electronics enthusiasts, so that you can exchange ideas with them. Please have a look at the Recommendations for Electronics Forums. I hope that one or more of them will suit your needs. And if you need help with troubleshooting, I have some tips on how to seek advice that may be useful.

Here are some recommendations for Practical Analog Electronics Books. Practical means that their focus is on teaching you how to design electronic circuits, and not so much on the theory and mathematics that you would need during an exam. Once you actually start to build your own circuits, you will find these Troubleshooting Resources and the recommendations for Introductions to Oscilloscopes useful. And for the construction of the circuits, some recommendations for Breadboarding and Prototyping will be useful.

If you want to understand the theory behind electronic circuits, the logical first step is to study basic linear circuit analysis. Once you have mastered it, you have a good foundation for studying the (much more interesting) analysis and design of electronic circuits. This will teach you the theory that you need to build your own circuits. It is also a good starting point if you want to design your own ICs, in this case you should proceed with some Introductions to Analog IC Design.

After theory and building real circuits, simulation is the 3rd pillar of analog electronics. By far the most important simulators are the many SPICE variants, please take a look at some recommendations for Circuit Simulations with SPICE. I highly recommend that you learn as early as possible their advantages and limitations. They are also a good way to start with electronics if your budget is very limited and does not allow to buy any equipment.

Op Amps are the first (and most important) device on which I will focus, here are some recommendations for General Op Amp Books and some Op Amp Applications. Not less important are passive components like the Resistor and the Capacitor. Of all semiconductor devices, Diodes are the easiest to understand. But you can already see the difficulties that come with a highly nonlinear characteristic. Circuits with transistors are more difficult. For analog circuits, the BJT (Bipolar Junction Transistor) is very common.

A very valuable resource, sometimes neglected by students, are the application notes and similar information from the big semiconductor companies. They will not be of much help to pass your exams, but will provide you with the necessary information if you want to design circuits in the real world. Some of them only cover a specific product, others like the Analog Devices Seminar Notes also discuss fundamental topics. Also very interesting are the Columns and Application Notes by Bob Pease and the Application Notes by Jim Williams. The free E-books and Application Notes from Texas Instruments include the famous Op Amps for Everyone.

For some areas of electronics, a solid knowledge of a few mathematical concepts is indispensable, so I will provide some mathematical resources too. I will, however, focus on the usage of mathematics as a tool, not on mathematical rigor and proofs. One of the most important mathematical tools for electronics are Complex Numbers. Once you have mastered them, analysing AC circuits (in their steady state) will be nearly as easy as the analysis of DC circuits. Another very important foundation for many areas of electronics is a basic knowledge of Calculus. During the following months I will add several other mathematical topics that have applications in electronics, but in the meantime you might want to look at the Mathematics for Physics and Engineering page - the resources there provide a summary of the most important topics.
