Well there is no such thing as a passive amplifier (as far as I am aware) as you need a power source to amplify. However I think you may be thinking about Passive pre-amps in audio applications. These are actually passive volume control circuits that take the place of traditional pre-amp circuits mainly because the signal output of cd's etc don't need an additional pre-amp stage so a passive volume control reduces cost and can improve sound quality (though this depends on how well you design the circuit).

My question is what is the meaning of passive op-amps? is the meaning of passive is no capacitances or inductances ? and what about meaning of second order passive amplifier?.
Thanx
Passive pre-amp can be audio pre-amp consisting of connectors, switch and potentiometer. Audio power amplifier with enough gain (giving max power at nominal audio level) does not need any amplification in pre-amp, only attenuation (potentiometer).
Passive op-amp is nonsense.

In electronics a term passive amplifier simply does not exist. Amplification must be made of active elements like transistors or operational amplifiers (op-amps) and no passive element can do amplification of electrical signal except transformer. But this was said in previous posts.
Passive op-amp (operational amplifier) does not exists. It's an active semiconductor device.
Tell us what you want to do with this passive amplifier. What should be it's main function?
