To the base of the switching transistor,, negative of zener snd a diode are a capacitor and sn inductor which are just shorted out, and one end is just floating... Would you plz. Check!?

Redrew your circuit..... http://everycircuit.com/circuit/5926962464555008

guys, in both of your circuits, what is the 30uF 1kOhm for, it has no impact at all!

That is what i asked earlier,. is Not connected to anything.

but this is also in your circuit kiani. Anyway, its just a little snuffer part. What i would simplify for this setup here is the current sink at out. The voltage is stable enough around 4V, so a simple resistor will do the job, and its already there in its size of the shunt ;-) both transistor are not really needed. It would be interessting for higher voltage ranges for more elastic.

I think got it dorted out. It is Ringing now......chk this.... http://everycircuit.com/circuit/5926962464555008
