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

A method in a low-noise amplifier (LNA), wherein the low-noise amplifier comprises:

• first and second input ports (Vinn, Vinp) respectively configured to receive a positive input voltage and a negative input voltage;
• a first resonance circuit, a second resonance circuit, a first transistor (M1) and a second transistor (M2);
• wherein a first voltage output port (Vop) of the first resonance circuit is connected to a drain of the second transistor, and a second voltage output port (Von) of the second resonance circuit is connected to a drain of the first transistor,
• wherein the first voltage output port and the second voltage output port are cross coupled to a second node of the first transistor and a second node of the second transistor via a first capacitor and a second capacitor respectively;
• wherein 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;
• wherein the method comprises:
• receiving, by the first input port and the second input port, differential input signal;
• and
• outputting, by the first voltage output port and the second voltage output port, differential output signal.
