hi all

can anybody suggest some good circuits for a beginner to study? ideally they should be devices that perform some interesting task, and whose functionning can be convincingly demonstrated. they do not need to be efficient: illustrating basic principles of circuit design is all i expect from them. (i promise i will not try to build anything that's just an instructional example.)

There is no right answer. Let your own interest be the guide. Every circuit shares most of it's principles with every other circuit, so it is less important to start with some objectively "correct" circuit than to just start investigating how things work.

 

The Art of Electronics has plenty of circuits, good and bad designs for one to explore.

Take your pick. The theory behind each circuit can be found in the corresponding section in the e-book.

I also recommend Art of Electronics as suggested by JoeJester.

It's always interesting to look at the application notes and datasheet circuits of the major semiconductor manufacturers. Scan the lists of appnotes at http://www.analog.com , http://www.linear.com , and http://www.national.com , to name just a few, and pick some that look interesting, to you, to download. Also, look at their "products" pages and drill down into the hierarchy and pick some that look appealing, to you, and download their datasheets. There are usually "typical applications" sections with circuits, in the datasheets.

Occasionally you can find a real gem; something that fits your level of understanding and opens up a whole new sector of technology, for you to explore.

Save all of the PDF files, somewhere, so you can do searches of them, later, after you know what to look for.
