Abstract
A capacitor-free fast-transient-response low-dropout voltage regulator (LDO) with dual-loop controlled paths is presented in this paper. This technique can make the transient response to be faster than other LDOs with traditional controlled loop. Especially, the performance of settling time of proposed LDO is excellent without off-chip capacitors. With 1.5 V power supply voltage, the output voltage is designed as 1.2V. The prototype of the LDO is fabricated with TSMC 0.35-mum DPQM CMOS processes. The active area is only 360 mum times 345 mum.
