Hi, I need to design a sawtooth wave oscillator, and I found this designe from http://hobby_elec.piclist.com/e_ckt17.htm [Broken](adsbygoogle = window.adsbygoogle || []).push({});

does anyone can show me how to get the equation, f=(1/2C(R1+R2))x(R3/R4) and also the osillator is valid for what range of the frequency, thanks.
