Abstract

The invention provides an inverter-based low-noise amplifier, a receiver and electronic equipment, and the low-noise amplifier comprises a first inverter, a second inverter and a third inverter; the input end of the first phase inverter is directly or indirectly connected with a signal receiving end, the output end of the first phase inverter is connected with the input end of the second phase inverter, the output end of the second phase inverter is connected with the input end of the third phase inverter, and the output end of the second phase inverter and the output end of the third phase inverter are connected with a frequency mixer, so as to output a differential signal to the frequency mixer; the first phase inverter, the second phase inverter and the third phase inverter are all CMOSphase inverters.

Description

Technical field[0001]The present invention relates to the field of signal processing, in particular to an inverter-based low-noise amplifier, receiver and electronic equipment.Background technique[0002]In order to support the exponential growth of data rates in cellular systems operating in the frequency band below 6 GHz, technologies that utilize parallel receivers have been introduced in electronic devices (such as mobile terminals), such as carrier aggregation and multiple input multiple output (MIMO, Multiple- Input Multiple-Output). In order to save pin count and circuit board space, electronic devices (such as mobile terminals) usually use single-ended input receivers. However, in order to enhance the ability to suppress common mode noise and interference, it is necessary to convert the radio frequency signal (ie, the RF signal) into a differential signal as soon as possible in the signal chain of the receiver.[0003]In the related art, an on-chip transformer (used as a balun) ...
