A Transient-Enhanced Voltage Regulator with Stability and Power-Supply-Rejection Boosting [PDF]

Nanoscale Research Letters, 2019
AbstractA high-stability voltage regulator (VR) is proposed in this paper, which integrates transient enhancement and overcurrent protection (OCP). Taken into consideration the performance and area advantages of low-voltage devices, most control parts of proposed VR are supplied by the regulated output voltage, which forms self-power technique (SPT ...
