Abstract

The invention discloses an ultra-low power consumption broadband low-noise amplifier, which comprises an input-stage amplifier, an intermediate-stage matching network and an output-stage amplifier sequentially connected; the input-stage amplifier is composed of an input matching network and a transconductance enhancement structure; the The output stage amplifier is composed of capacitor neutralization structure and output matching network. Through the above method, the present invention can improve the efficiency of current use, and greatly reduce the power consumption of the amplifier while ensuring performance such as gain and noise. On the other hand, it optimizes the matching between amplifier stages, increases bandwidth, and reduces in-band fluctuations.

Description

technical field [0001] The invention relates to the technical field of electronic circuit design, in particular to an ultra-low power consumption broadband low-noise amplifier. Background technique [0002] In recent years, the new generation of communication technology has achieved rapid development, and the low frequency band can no longer meet the needs of high-speed communication. The millimeter-wave frequency band is rich in spectrum resources and has become a research hotspot, such as millimeter-wave 5G communication and broadband satellite communication. In millimeter wave communication, it is a key issue to ensure the signal-to-noise ratio of the received signal. [0003] The low-noise amplifier is the first active device in the receiving channel, usually directly connected to the receiving antenna, and plays a decisive role in the overall noise of the receiver. In order to reduce the impact of the noise of the receiver's post-stage, the low-noise amplifier needs t...
