Abstract
Provided are a low noise amplifier and a receiver. The low noise amplifier comprises at least one input port configured to receive an input signal including a carrier, first to third output ports connected to first to third load circuits, respectively, and configured to transmit an output signal, a first amplifier stage comprising a first type gain stage connected to the input port and first to third first type drive stages connected to the first to third output ports, respectively and second to third amplifier stages, each comprising a second type gain stage and a second type drive stage, wherein the low noise amplifier is configured to vary an impedance of an input transistor included in each of the first type gain stage and the second type gain stage, so that an input impedance is uniform even when operating in a plurality of operation modes.
