Abstract

this paper proposes a new dual-mode low-dropout linear regulator without external capacitors, which includes three error amplifiers, an offset voltage generator, a mode decision circuit, and a pre-biasing load transient enhancement circuit. The chip uses a 28nm CMOS process to verify the advantages brought by the architecture of this work. The measurement results show that the output voltage has a negligible undershoot and overshoot (both less than 5mV) during mode transition. In load transient response, due to the use of pre-charge technique, the output voltage undershoot and overshoot are reduced by 45.2% and 36%, respectively. Finally, this architecture achieves FoM to be close to 1fs.
