Abstract
Official abstract text for this publication.
A low noise amplifier comprises at least one amplifying transistor (Ts 1 ; Ts 2 ) configured in a common source configuration to receive an input signal (RFin) at a gate terminal and provide an amplified signal at a drain terminal and at least one feedback path arranged to couple a part of the amplified signal back to the gate terminal and comprising a feedback impedance. The low noise amplifier further comprises a self-coupled step-up transformer having at least one primary winding (Lp) connected to a supply voltage (Vdd) and the drain terminal of the at least one amplifying transistor and at least one self-coupled secondary inductor winding (Lf 1 ; Lf 2 ) arranged in the feedback path. The low noise amplifier provides a better suppression for out-band interference and at the same time it has a wider input match bandwidth, decent conversion gain and decent noise figure without increasing power consumption.
