| Abstract: | This paper is intended to improve the regular structure of driving circuits by an analysis of factors that cause instant power drop of voltage in the multiple output of digital IC chips.As the peak current of the improved single output will be dropped by one third,it will along with an optimum pattern of routing,effectively prevent power voltage from decreasing so as to achieve a normal and stable efficiency of performance for the chips. |
