• Fast-transient response
• Active feedback
• Shunt regulator

The dual-loop shunt regulator using current-sensing feedback techniques is proposed in this paper. This architecture adopts a voltage and current loops to increase the transient response of the proposed shunt regulator. The maximum output current of the proposed shunt regulator is 180 mA at a 1.8 V output. Moreover the architecture of the proposed shunt regulator can suppress the stray effect which is from power supply. The prototype of the proposed shunt regulator is fabricated by the Taiwan Semiconductor Manufacturing Corporation (TSMC) 0.35-mu m CMOS 2P4M process. The active area is only 579 x 355 mu m(2).
