you need to state the entire specification
you stated the output
what is the input? is it AC or DC?
if it is AC, what frequency range?
since it is an amplifier, what is the required gain?
what voltage are you using to power the op-amp?
you need to show what you did.
schematic at a minimum (with parts clearly labeled)
the calculations you did for the circuit
simulations if you have them
the more complete the information, the more likely
you'll get useful help
since it is an op amp circuit, look at this:
**broken link removed**
its the National Semiconductor Linear applications Handbook
I had one on my shelf for years.
or this
Handbook of Operational Amplifier Applications from Texas Instruments
it is a pdf
