I want to amplify a electrical signal which have millivolt voltage.That is signal from IR sensor.I want to produce an IR intensity meter therefore I need to amplify voltage given by IR sensor into approximately 5V can any one give a circuit diagram for do this?

MOD: Post Moved to correct section
 

Help me to amplify.

Wrong group dude, this is digital design ONLY.
