Description

technical field [0001] The invention relates to the technical field of integrated circuits, in particular to an integrated circuit of a current-multiplexing gm-boost low-noise amplifier. Background technique [0002] In the radio frequency wireless communication receiving system, the low noise amplifier, as the first stage active circuit, needs to have very low noise and provide sufficient gain to amplify the weak radio frequency signal and suppress the noise of the subsequent stage circuit. [0003] With the continuous evolution of wireless communication technology, in portable communication tools, the requirements for comprehensive performance indicators of power consumption, gain and noise of low-noise amplifiers are getting higher and higher, and high-performance low-noise amplifier integrated circuits have great practical value , which is a hotspot of research in both the commercial field and the scientific research field. [0004] However, the key indicators of the lo...
