Low-noise amplifier, receiver and method in a low-noise amplifier

摘要

A low-noise amplifier comprises first and second input ports respectively configured to receive a positive and negative input voltages; first and second resonance circuit, first and second transistor; wherein a first voltage output port of the first resonance circuit is connected to the second transistor, and a second voltage output port of the second resonance circuit is connected to the first transistor, the first and second voltage output ports are crossed coupled to a second node of both the first transistor and the second transistor via a first and second capacitor respectively; the second node of the second transistor is connected to both the second input port via a third capacitor and a third node of the first transistor, and the second node of the first transistor is connected to both the first input port via a fourth capacitor and a third node of the second transistor.
