Abstract
An LNA for use as an input stage of a radio frequency tuner comprises an inverting amplifier stage and a transconductance stage. The amplifier stage has an input connected via an input resistance to an input of the amplifier and via a feedback resistance to an output of the amplifier stage. The transconductance stage passes a current through the input resistance which is substantially proportional to the output voltage of the amplifier stage.
