Abstract
Apparatuses and methods of current balancing, current sensing and phase balancing, offset cancellation, digital to analog current converter with monotonic output using binary coded input (without binary to thermometer decoder), and compensator for a voltage regulator (VR), are provided. In one example, an apparatus includes: a plurality of inductors coupled to a capacitor and a load; a plurality of bridges, each of which is coupled to a corresponding inductor from the plurality of inductors; and a plurality of current sensors, each of which is coupled to a bridge to sense current through a transistor of the bridge.
