An ultra-fast 65nm capacitorless LDO regulator dedicated for sensory detection using a direct feedback dual self-reacting loop technique

Abstract

This article presents an ultra-fast 65nm LDO regulator dedicated for sensory detection using a direct feedback dual self reacting loop technique. This novel technique enabled the regulator to achieve a very fast response time of 0.10μs for a maximum load current transition from 1 to 50mA. Furthermore, it achieves a very low quiescent current of 5.0μA coupled with a low power consumption of 5.0μW. This LDO regulator, simulated with Global Foundries 65nm CMOS process, yields a stable output voltage of 0.8V with a supply voltage ranging from 1-1.4V. Its distinct features, ultra-fast response time and very low power consumption, make it ideally suitable for sensory detection.
