Abstract
Some aspects of the present disclosure relate to a low-noise amplifier (LNA) having a balun configuration. The LNA includes a DC current path coupling a first DC supply node to a second DC supply node. First and second output nodes and first and second input nodes are spaced apart along a length of the DC current path. A single-ended radio frequency (RF) input terminal is configured to deliver a single-ended RF signal to the first and second input nodes. A differential RF output terminal is made up of the first and second output nodes. The first and second output nodes are configured to cooperatively establish a differential output signal based on the single-ended RF signal. Other devices and methods are also disclosed.
