Abstract :
A silicon tuner has been designed for the reception of analog or digital TV signals from a cable or a terrestrial network. It exhibits 5 dB NF over the 42-870 MHz frequency range and integrates a self-calibrated LC tracking filter. This allows 55 dB video SNR under fully loaded spectrum conditions. The (N + 1) image channel is rejected by more than 62 dB thanks to a fully integrated full complex mixer with auto calibration. The 5.7 mm2 active die is fabricated in 40-GHz fT BiCMOS 0.25 mum technology and dissipates 780 mW running from a 3.3 V supply.
