Abstract

PURPOSE: To provide a device for preventing peak current from concentrating to a trunk wiring of power source and smoothing the current by providing sufficiently large capacities on the line close to the peak currentgenerating source.
CONSTITUTION: A trunk wiring DO from a power source VDD has three branch wirings DA, DB and DC, which respectively are connected to circuit blocks A, B and C and further to wirings GA, GB and GC supplying electrical potential VSS, with capacities CA, CB and CC provided inbetween for the purpose of smoothing peak current. The provision of each capacity between the two corresponding wirings near to each circuit block serves to charge or discharge peak current components and smooth the current. This device is, accordingly, advantaged by allowing a wide range to the maximum change of voltage depending on the peak value of current and lengthening the life of wirings depending on the mean square of current.
