Circuit analysis of the video monolithic amplifier

From rsers' point of view, for correct using of linear integrated circuits, we have analyzed the video amplifier made already. As this amplifier is three stage direct coupling with feedback circuit, we have divided this circuit into a forward network and a feedback network. And then we have obtained the transfer function of each network, so that using those, we have obtained the total transfer function. Hence we have compared the calculated data of this total transfer function with the mesured data, and we have made sure that these two results are approximately agreeable.
