LDO less non capacitive on-chip dynamic output voltage regulator for self-powered IoT applications

In this paper, a LDO less non capacitive dynamic output voltage regulator has been proposed for self-powered IoT applications. Strong arm latch has been employed to provide a regulated supply to the load from an energy harvester continuously. It diverts the harvester's energy to a storage unit in case of excess energy available than the load requirement and supplies this stored energy back to the load in case energy harvester is not able to supply the load requirement continuously. The simulations have been carried out with LTspice in 0.18µm CMOS technology using tsmc model.
