How could I make this (or any type of diy oscillator) oscillate at a higher frequency? It seems to be extremely difficult to achieve this, because it won't oscillate at all unless you have enough phase shift, and so all the caps/inductors/ and or resistors, can only go so small before the oscillations die out. Is there another way I'm not aware of to get an oscillator to oscillate at higher frequencies, other than using smaller caps/inductors/resistors? ...Or does it have to do with this particular design I came up with?
