Well,I want to study the basic principle of oscillator and learn how to design it and what should I give my attention to during the design,I am new in oscillator field,so can someone recommend me a good book of learning oscillator?Thanks.
I recommend the book: Oscillator Circuits by Graf,
though the book was not so informative, it has various examples and circuit diagrams of various types of oscillators....
I recommend the book of J. Rogers and C. Plett. It is a blue one and its name was i guess "Radio Frequency integrated circuit design" or something like that
