Abstract :
This paper proposes a new input-side current sensing method for the voltage regulator (VR) to achieve adaptive voltage position (AVP). By applying the proposed method, both good current sensing accuracy and low power dissipation can be achieved. The transient and tolerance analysis of this method are provided and a design guideline is illustrated and experimentally verified
