Abstract

A device for reducing the electromagnetic emission in integrated circuits having driver stages reduces the electromagnetic emission of an integrated circuit without requiring an increase in the blocking capacitance in the process. This is achieved by combining driver stages which do not switch simultaneously to form driver groups, and special wiring of a plurality of blocking capacitors.
