A greater overall gain-bandwidth product Cor multistage amplifiers is
realizable through a design procedure that characterizes the total amplifier rather

The increase in gain- band width product will be shown to result from the
shrinkage factor is the ratio of overall amplifier bandwidth to the intorstage band-
