  • Output buffer circuit
    Patent number: 8373455
    Abstract: An output driver circuit can include at least a first driver transistor having a source-drain path coupled between a first power supply node and an output node. A first variable current supply can generate a current having at least one component that is inversely proportional to a power supply voltage. A first driver switch element can be coupled in series with the first variable current supply between a gate of the at least first driver transistor and a second power supply node.
    Type: Grant
