I have a 5V supply, i want to get an 5.7V/ 6V out of it!
and i cant use a amplifier because the only voltage i get nearby it is 5V.
Though seems to be something like foolish, thats what i need to do.
Application: Want to charge a mobile rated to 5.7V supply voltage;
if 5V volts does the job, then i want to know whether the above this is possible?
Like if i use a ossilator and again a rectifier?
If you want an accurate voltage, get an old car-phone-charger. It has a chip that will convert 5v to any voltage you want. Just adjust 1 or 2 resistors. It has a chip and an inductor and will do waht you want. They cost about $3.00

Can't i vary the resistor, capacitor value and get the suitable output?
My ques is: My gadget is to be charged with 5.7V and 500mA
What if i charge with 5.7 and 350 mA/ something with other output current ?
I suppose you're not talking about resistor networks are you? A bit puzzled here, since if it is, I can't see any complexity in that. Sorry for barging in.
A resistive voltage divider is totally unpractical at your current requirements. Even a linear regulator would produce (48-36)*15= 180W of heat. This would require a huge heatsink.
This is a job for a SMPS buck converter with an overall efficiency of ~85% which would reduce the power dissipation to about 30W.
