摘要： An overdrive control system includes a voltage controlled current source to deliver a compensation current, and being between a first voltage reference and an internal node, which is connected to an output terminal. The voltage controlled current source has a control terminal connected to an output terminal of an adding block, which has a positive input connected to an input terminal. At least one clamping block is between the output terminal and a second voltage reference, and is connected to a negative input of the adding block. The voltage controlled current source delivers its compensation current to the output terminal when a voltage signal on the input terminal has an higher value than a voltage signal on the output terminal, and forces an output voltage signal to follow an input voltage signal to an extent that depends on a clamping voltage provided by the clamping block.
