The pros and cons of various OPA architectures

[safwatonline]

hello,
what are the main adv. and disadv. of different OPA architectures
i.e. i want to know how to choose to go to a certain architecture and not the others,i mean like telescopic ,folded, cascaded, gain boosting...

in terms of gain ,BW, swing , current consumption , SR,.....

thanks
