The question is as follows, investigate and research the effects off applying feedback to single and multi staged electronic circuits. I am Seriously Not sure about this question and i realy need help!!!! pleaseee!!!

 

Feedback is necessary because open loop gain is extremely high and inconsistent amongst opamps. Try to find a lecture on opamps via google, "opamp design lecture filetype: pdf"

i cannot find anything regarding your comment, i cant seem to find any information on the internet relating to the question, can you please help em further??

Out of the 567,000 hits on "feedback in amplifiers", the first one is pretty good - http://en.wikipedia.org/wiki/Feedback_amplifier. It includes useful links.

 

Yeah, sorry, the search I wrote had a space between filetype: and pdf, there shouldn't be one. I found an okay link

Thanks people, is there anyway i could prove this by using suitable example circuit diagrams?

 

Looks like one of your colleagues has asked the same question recently: http://forum.allaboutcircuits.com/showthread.php?t=8706

My advice is as given in that thread.
