Abstract: Some embodiments include apparatuses and methods having a power switching unit to receive a first voltage and provide a second voltage having a value based on a value of the first voltage, a first loop to provide digital control information to control a switching of the power switching unit in order to maintain a relationship between the value of the second voltage and a value of a reference voltage, and a second loop coupled to the power switching unit and the first loop to calculate a value of energy consumption of at least a portion of the apparatus based at least on the digital control information.
