Abstract

The invention discloses a low power consumption radio frequency front-end integrated circuit oriented to NB_loT. The circuit comprises a low noise amplifier, a frequency mixer, an intermediate frequency filter and an intermediate frequency amplifier; in the existing receiver structure, superheterodyne receiver is complex in structure and large in power consumption, so that only the zero intermediate frequency structure is most direct and natural. The zero intermediate frequency structure is applied in the low frequency range of the sub1G to realize low power consumption and high integration density. And meanwhile, the influence from the DC disorder is eliminated by introducing a DC negative feedback technology for the specific DC disorder problem of the zero intermediate frequency structure.

Description

Technical field [0001] The invention relates to the related field of integrated circuits, in particular to a low power consumption wireless radio frequency front-end integrated circuit for NB_lot. Background technique [0002] With the development of communication technology, mobile communication is moving from the connection between people to the connection between people and things and things and things. The interconnection of everything is an inevitable trend. Among them, NB_loT technology focuses on the low-power and wide-coverage IoT market, with features such as wide coverage, multiple connections, low speed, low cost, low power consumption, and excellent architecture. [0003] The existing receiver structures mainly include superheterodyne receivers and zero-IF receivers. The zero-IF structure is the most natural and direct realization of the receiver, and it is a scheme that directly down-converts the radio frequency signal into a baseband signal. The block diagram of the...
