Abstract
A final stage for a high-speed comparator, and a method of driving an electric load having a capacitive component are disclosed. The final stage comprises a first or pull-up component and a second or pull-down component which are connected in series with each other between a first or supply voltage reference and a second voltage reference. A dynamic drive device and a separate static drive device are coupled to each component of the output stage. Each component of the final stage is driven separately according to whether it is in a static or a dynamic load condition.
