Oh 20ms that's much better.
Yes the CMOS timer will use much less power to run.
If you want to drive one or more LEDs you'll have to see if you end up with enough voltage across the cap. If not you'll have to look into ways to step up the capacitor voltage enough to drive the LEDs.
BTW how did you get that waveform, with a scope? And what kind of load did you use with the scope other than the scope itself?

I tried the transformer but the results are very bad since the output of the transformer was distorted. It seems that I have chosen the bad transformer characterestics. How should I choose the transformer?
Oh i see ok, so you used a 1 ohm resistor as the load for those waveforms. So we can read that graph as current too without any scaling.
The CMOS timer is a 555 but a CMOS version not the bipolar version.
Transformers are simple devices but there are some side effects during the first cycle or first few cycles and afterward that might be hard to deal with. What kind of transformer did you try?

The transformer I used has a 30mH winding on one side and a 845 mH on the other side. I don't know the number of turns on each side.The step-up ratio is 5.
I made a FFT for my waveform signal and it appears as if it contains the most power in its 60HZ content. So I may say that a ferrite transformer is no good for my application since this is a low frequency signal.
