Title: CONFIGURABLE, LOW-POWER CONSUMPTION, ALL-DIGITAL TRANSMITTER
Abstract:
The present invention relates to the technical field of wireless communication, and specifically provides a configurable, low-power consumption, all-digital transmitter. The configurable low-power consumption transmitter of the present invention mainly comprises circuit modules, such as a configurable baseband signal processing circuit, a coordinate conversion circuit, phase pre-distortion calibration, a phase modulation module, an oversampling and noise shaping module, an amplitude control logic module, an all-digital dual-power differential power amplifier, a passive matching network, a low-dropout linear regulator, an all-digital frequency synthesizer, a serial peripheral interface, and an output load. The transmitter has flexibly reconfigurable circuits (mainly comprising a reconfigurable baseband signal bandwidth, a reconfigurable radio frequency point, reconfigurable transmit power, etc.), and thus can meet the application requirements of different wireless communication standard protocols (such as Bluetooth Low Energy (BLE) technology, Wireless Body Area Network (WBAN),cellular-based Narrow Band Internet of Things (NB-IoT), and 802.11ah). Furthermore, the transmitter is simple in structure, has all circuits being digital, has the advantages of low power consumption, high integration, and low costs, and is easy to be applied in an actual wireless communication system.
