Enhanced low noise amplifier

Receiver for digital television signals comprising an analog front end and a demodulation unit, characterized in that said analog front end comprises at least one amplifier for radio frequency signals comprising a first stage being connected between the input, a ground and an output and a second stage being connected between the output and a direct voltage source, and wherein said second stage provides a direct current path with a first inductor, the circuit further comprising a first capacitor connected in parallel with said direct current path and a second inductor series-connected with a second capacitor wherein the values of said first and second inductors and of said first and second capacitors are set to have predetermined ratios to amplify the signals within a first range of frequency and simultaneously attenuate the signals within a second range of frequency and wherein each of the couples of inductor and capacitor allows setting of respectively the central attenuation frequency and the central amplification frequency.
