Abstract

A gradient detecting unit detects the gradient in the output of a driven circuit. An offset voltage generating unit generates an offset voltage in response to an output of a driven circuit as well as the gradient detected by the gradient detecting unit. The gradient in the output of the driven circuit is increased as the change thereof is more abrupt and decreased as the change thereof is more gentle. For example, if the detected gradient is added to the normal offset voltage to form an offset voltage, the offset voltage can follow the changes in the output of the driven circuit to supply a proper supply voltage to the driven circuit.
