Abstract
- Summary: This paper presents an output capacitor‐less low‐dropout regulator (LDO) with wide load capacitance and current ranges. A new Miller compensation technique called multipath double‐nested Miller compensation with Q‐reduction circuit is introduced to extend the ranges of the load capacitance and current. Besides, a multiple small‐gain stages technology is applied to improve the loop gain of the LDO, achieving better management accuracy. The proposed LDO was fabricated in a 130‐nm CMOS process. The measured maximum load capacitance can be extended to 4.7 nF, and the maximum load current is 80 mA. Moreover, the measured line regulation and load regulation are 4 mV/V and 0.154 mV/mA, respectively. [ABSTRACT FROM AUTHOR]
