Patent ID: 8901972

Claim:
A transition driving circuit that selectively switches sources of current depending on information regarding a voltage transition to increase the linearity of voltage through the voltage transition, comprising: a first source of current coupled to a first switch and a second switch; a second source of current coupled to a third switch and a fourth switch; a first driver coupled to a high reference voltage, the first switch, the third switch, and an output to generate a high voltage at the output; a second driver coupled to a low reference voltage, the second switch, the fourth switch, and the output to generate a low voltage at the output; and a controller that is configured to receive voltage transition information and to selectively turn on and turn off the first switch, the second switch, the third switch, and the fourth switch to select an amount of current for the voltage transition depending on a magnitude of the voltage transition to reduce overshoots or undershoots in the voltage transition.
