Abstract: Described is an apparatus which comprises: an amplifier to receive a reference voltage; and calibration logic which is operable to receive a first voltage and to provide the reference voltage to the amplifier, wherein the calibration logic is operable to generate a look-up table (LUT) that maps the first voltage to a drive current.

Abstract: In an embodiment, a system includes voltage sensing logic to determine a first source voltage Vfirst source corresponding to a first source, and a controller to receive an indication of Vfirst source from the voltage sensing logic. The controller is to, responsive to Vfirst source>a first output voltage (V1), select a first source first regulator to input Vfirst source and provide V1; responsive to Vfirst source>a second output voltage (V2), select a first source second voltage regulator that inputs Vfirst source, and provide V2; responsive to Vfirst source≤V1, select a second source first voltage regulator that inputs a second source voltage Vsecond source that corresponds to a second source and is substantially constant in time where Vsecond source>V1, and provide V1 independent of the first source first regulator and the first source second voltage regulator. Other embodiments are described and claimed.

Abstract: Described is an apparatus which comprises: a source to generate a first current having AC and DC components; a current-to-voltage converter to convert the first current or a copy of the first current to a first voltage proportional to a resistance, the first voltage having AC and DC components that correspond to the AC and DC components of the first current; a sample-and-hold circuit to filter the AC component from the first voltage and for providing an output voltage with the DC component; and an amplifier to receive the output voltage.
