ABSTRACT:
An output circuit is constructed such that a load capacitor is not charged by an external power supply but by a first charge storage element within a semiconductor chip that is charged before the load capacitor. The charge stored in the load capacitor is released not directly to the ground but to a second charge storage element within the semiconductor chip and discharged before discharging of the load capacitor.
