Abstract
An electronic device for controlling oscillation of an output voltage about a final value includes a semiconductor substrate, and at least one output stage on the semiconductor substrate. The at least one output stage includes at least one output transistor for providing an output voltage to an external load connected thereto. The output transistor includes a plurality of transistor legs connected in parallel and having different channel lengths. Each transistor leg is individually turned on and at different times for controlling oscillation of the output voltage about the final value.
