Abstract
Methods, systems, and structures for generating a target reference voltage are provided. A circuit includes a voltage adjuster, a switch, and a current source. The switch selectively connects the current source to circuit paths in the voltage adjuster. A first of the circuit paths incrementally decreases the target reference voltage with respect to the input voltage. A second of the circuit paths incrementally increases the target voltage with respect to the input voltage.
