Hi,

I encountered a lecture note in the web discussing about an oscillator circuit using LCCC. It looks like in parallel configuration with one capacitor in parallel with the L,C,C in series. But the text says the L,C,C,C are all in series and continues quickly to give its natural frequency formula without derivation.

So I did the derivation for the series case, and indeed it matched the formula. Then I derived for the parallel case and found it gave the same result. I am perplex. Does this means we can compute for the parallel and the series in either way?
