Abstract
A low-noise amplifier (LNA), a folded low-noise amplifier (folded LNA) and an amplifier circuit module are provided. The LNA includes a plurality of radio frequency (RF) input stages, at least one bias transistor and at least one radio frequency (RF) output stage. The bias transistor is connected to the RF input stages to provide a DC bias source to one of the RF input stages for isolating others of the RF input stages. The RF output stage is connected in parallel with the RF input stages, which share an adjustable input inductor.
