Hello I am trying to understand how exactly an oscillator circuit work and how to build one. So I was palying around in falstad and made this: the following is link. tried to get around spam filter so.. write without spaces h t t p s : / / w w w . f a l s t a d . c o m / c i r c u i t / # and add: %24+1+5.0E-6+10.20027730826997+54+5.0+50%0Ac+208+176+208+288+0+1.0E-5+-1.5725275170777988%0Ar+320+176+320+288+0+100.0%0Aw+320+288+208+288+0%0AR+320+288+512+288+0+0+40.0+5.0+0.0+0.0+0.5%0Al+208+176+320+176+0+1.0+-0.011516250308585715%0Ag+320+176+496+176+0%0AO+208+176+160+176+0%0Ao+0+64+0+35+20.0+0.025+0+-1%0Ao+0+64+0+35+20.0+0.05+1+-1%0A As it is visible from circuit simulator, only a capacitor, inductor and resistor is used to create non-ending sinus waveform from DC. Question: would this actually work in real circuit? And if so, then why every example of oscillator circuit online includes at least one transistor and few more capacitors and inductors? thank you.
