More Information
Summary:An example apparatus includes a feedback loop to: change a direction value when a second current value is greater than a first current value, the second current value being obtained after the first current value; and maintain the direction value when the second current value is less than the first current value. When the direction value corresponds to a first direction value, a summer increases a reference signal by a step size. When the direction value corresponds to a second direction value different than the first direction value, the summer decrease the reference signal by the step size.
