Abstract
A slope generator generates, in response to an input signal, a slope between a first and a second voltage level of an output voltage at an output node. The slope generator comprises a capacitor coupled to the output node, a first current source for providing a first current to the output node, and a second current source for providing a second current to the output node controlled by a first current switch. A control electrode of a first current path of the first current switch is coupled to and controlled by the input signal, a second current path is coupled to the output node, and the first current switch provides the first and the second voltage levels, or corresponding voltage levels derived therefrom, to the output node.
