hello there
i have to do a project at my school and i need some help.the project is that i should design a circuit with amplifiers,converter dc to dc,sine signal from 2,5-5 volts and should convert it to the output in sine signal from 0-6 volts and it should be in the same phase as the input signal.i was thinging to do it with operational amplifier,but how i will take the output 0 volts when i give in the input 2,5 volts should i use voltage divider?i am confused any help will be apreciatable
