Abstract

The invention provides a multi-mode reconfigurable ultra-wideband integrated transceiver for realizing time difference distance measurement, frequency difference distance measurement, phase difference distance measurement and wireless communication based on a sub-module integrated integration technology, and provides two realizable innovative transmitter architectures. The multiplexing degree of the integrated transceiver exceeds 90%, the resolution is higher than that of an existing transceiver, and the deadline that a traditional transceiver is low in resolution is broken through. The invention aims to realize the functions of a communication chip and a radar chip by using the area and power consumption of one chip through a sub-module co-architecture integrated design. According to the two innovative transmitter structures, some simple digital modules are used for replacing relaxation oscillators, the power consumption is greatly reduced, and the reusability is high. The low-power-consumption design based on current multiplexing enables the system to be applied to an ultra-low-power-consumption scene, innovatively breaks through the advantage of low resolution of a traditional transceiver, and also enables the system to be applied to a high-resolution scene.
