Dual stage low noise amplifier for multiband receiver

A method for providing amplification in a multiband receiver, the method comprising:

• amplifying at a plurality of amplifiers carrier signals received by each antenna of at least one antenna, the amplified carrier signals being output from a respective plurality of output ports of the plurality of amplifiers,
• wherein each amplifier of the plurality of amplifiers comprises at least first and second transistors;
• wherein a first capacitor is coupled between an input of each amplifier of the plurality of amplifiers and a gate terminal of the first transistor;
• wherein a second capacitor is coupled between an input of each amplifier of the plurality of amplifiers and a gate terminal of the second transistor;
• controlling a plurality of switches to control how outputs from the plurality of output ports are input to a plurality of demodulators having a respective plurality of input ports,
• wherein at least one of the plurality of output ports of the plurality of amplifiers is selectively coupled to any of multiple input ports of the plurality of input ports of the plurality of demodulators.
