you can adjust frequency by changeing value on the most left voltage source. this circuit grantee 50% width. At the left lm324. At the right located comparator lm393 and logic 74hc14. https://easyeda.com/AlexeyCu/oscillator

I tried to make a square VCO and filter the harmonics so as to leave out a sine wave but it didn't quite work. I have never seen such a sine VCO because EC lacks a varactor diode. If Igor decides to add a varactor diode, then we could make freq. synthesizers, FM mods and many more.
