Abstract
The design of passive NB-IoT system based on wireless power transmission (WPT) technology is presented. The above system consists of a transmitting module and a receiving module. The transmitting subsystem is composed of a microwave power generator and a transmitting antenna. The receiving subsystem is composed of a receiving antenna and a rectifying circuit. In this paper, the voltage conversion, energy storage and power management are realized by using an efficient power management (PM) circuit in the rear stage of the rectifier circuit. It provides 3.6 V to supply the NB-IoT device.
