Besides the earlier suggestions - pls download all the application note by Texas Instruments on Operation Amplifiers - it can provide you complete circuit diagrams and other theoretical stuff.. Im sure it may solve all of your problems !!!!! All you need is time and good net speed to download all the AN's

An operational amplifier is a component, therefore the circuit diagram for it is simply it's symbol, which is a triangle pointing to the right. If you want a particular amplifier circuit using an op-amp, then you'll need to be a bit more specific.

How much detail do you want? A very simple & crude differential amplifier circuit schematic can be found at the first link (usually a current mirror transistor circuit is used in place of the 1.5 K ohm resistor you see at the bottom, but you get the idea). The second link gives you the common 741 Op-Amp circuit schematic (near the bottom of the page).
====edit===
In case you don't know what a "current mirror" constant current source is, the third link should explain it.
A large resistor (such as the 1.5 k ohm resistor in the diagram at the first link) is a crude approximation to a constant current source, and it should do if you are not that concerned with performance.

You need a bit more detail to answer your request. What source voltage you will be using. A/C? D/C? What are you driving with the signal?

There is so many basic electronics book around.
