how to simulate an operational amplifier power dissipation?by the way, where to download "CMOS circuit disign,layout,simulation"book? thank you very much.
 

Put a zero-volt voltage source in series with all the op-amp stages and then measure the currents through them.
This will give you power per stage - by V*I (of course) and is more useful, than just finding the total power for the opamp.
