Hello

If anyone can recommend me a good book from which i will learn to construct
oscillator that for example covers range 0-12 MHz.

Thanks in advance!

12 MHz is easy. 0 MHz is really difficult.


Zero MHz is real easy, just throw a capacitor, transistor,
resistor, tube, or any other electronic component on the bench.
There, an oscillator that oscillators at zero MHz.

The ARRL Handbook (any edition).
The Art of Electronics.

Two of the best basic electronics books ever written

If you read my original post again or at least the topic, it says 0-12 (not
0, 12) MHz. And that would mean something in the range between 0 and 12. I
don't remember when and WHERE i said that i need 0 MHz oscilator. The only
one who talks about 0 MHz osc is you.

Perhaps English is a second language for you, but when you say 0-12 that
will be taken to mean those two frequencies and everything in between.


0 hz is hardly a 'frequency.'

Big thanks to all other people who gave me good starting points. I was
thinking about some CMOS devices, but most of them are square output.


Feed the square output to a coil+capacitor in parallel and you'll get
a sine wave. Tune the this 'tank' circuit for harmonics of the
funamental and you can double, triple, quadruple and so on the
original square wave's frequency.

Thank you Paul! This is a good hint. Can you tell me in which book did you
learn it? I would really like to get into this stuff.

On its way here...

The Art of Electronics.


I have this one and im not too happy with oscillator chapter. However, this
is still one of the best books i've seen.
