Abstract
The present invention belongs to the field of IoT (Internet of Things) chips, and discloses a BLE protocol-based battery-free multi-mode transceiver including a wireless energy harvester module, a power management module, a transmitter, a receiver and a backscattering module, where the wireless energy harvester module supplies power to the whole transceiver; the power management module provides required stable currents and voltages for circuits; the transmitter modulates a baseband signal inputted by an external device into a GFSK modulated Bluetooth intermediate frequency signal compatible to a BLE protocol, modulates a received continuous waveform signal by using a backscattering technology, backscatters digital information compatible to the BLE protocol, and transmits a Bluetooth radio frequency signal; the receiver receives the Bluetooth radio frequency signal, amplifies the Bluetooth intermediate frequency signal in an output of the rectifier, and demodulates the Bluetooth intermediate frequency signal to a Bluetooth baseband signal.
