Ok, well many circuit I have seen do not take advantage of the inductor discharge, and keeps cherging the capacitor from empty. I would like in my circuit to be able just to add the lost voltage to keep the oscillation going. In my circuit when the voltage falls below a certain point, it recharge the circuit.. but how do I know it is recharging the capacitor and that it is not being sent when the capacitor has just finish discharging. ( I think that if the circuit sends power to the capacitor when it has just discharge in the inductor, the frequency will jump a bit .. maybe I am wrong..)
