As part of Internet of Things (IoT) transformation, RFID is widely used. In the application where power supply is limited, power consumption is always a remarkable criterion as analog circuits and RF are the common power demanding parts in the system.

In the design of energy harvesting rectifier circuit, the use of zero-threshold negative channel metal oxide semiconductor (NMOS)s in 18-stage rectifier circuit is improved. The high efficiency regulator circuit is added to work directly with rectifier circuit. When the energy accumulation in the charge bank that is supplied by rectifier circuit is enough, only then the regulator circuit start to produce constant voltage.
