circuit for sawtooth oscillator

sawtooth oscillator

I want to build a sawtooth oscillator using only simple components like C,R,L and transistors (preference for bi-polar not Cmos)-no opAmp or 555 or any other chip.

Does anyone has an idea or a circuit diagram for it?

Thanks

If the German language is a problem, or the circuit schematics do not "speak" for themselves, you may use an on-line web page translator like babelfish, google or others like here:

He said no 555

no opAmp or 555 or any other chip.

Unijunction transistor is often used
