Ultralow-power consumption constant-envelope transceiver system and implementation method thereof

Abstract

The invention discloses an ultralow-power consumption constant-envelope transceiver system and an implementation method thereof. The ultralow-power consumption constant-envelope transceiver system comprises a stacked current duplex module, a passive frequency mixer, an adaptive gain frequency mixer, a reconstructable filter, a peak detection module, a phaselocked loop and a transceiver antenna, wherein the stacked current duplex module is provided with a voltage-controlled oscillator, a frequency divider, a low-noise amplifier and a power amplifier. In the invention, a large number of modules in the transceiver system are integrated, current duplex and module reconstruction are realized at multiple places, a receiver automatically regulates a bias current according to the intensity of a received signal, and thus, the dynamic regulation of power consumption is realized to realize the ultralow power consumption of the entire receiver. Compared with the conventional transceiver system, the system has ultralow power consumption, a simple structure and convenience for design.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, relates to a wireless communication system transceiver module and a radio frequency integrated circuit, and is an ultra-low power consumption constant envelope transceiver system and its realization method. Background technique [0002] In recent years, driven by the rapid development of portable electronic devices such as notebook computers and mobile communications, as well as WSN and GPS, low-power transceiver systems have become one of the important development directions of radio frequency integrated circuits. Researchers at home and abroad mainly realize the design of low-power radio frequency integrated circuits from the following perspectives. First, from the perspective of changing the process, such as using BiCMOS and multi-threshold voltage processes, but these methods are more expensive and the latter is more expensive. Manufacturability is poor; second, from the perspe...
