Abstract :
An integrated RF tracking filter based upon a programmable LC resonator and an auto-calibration is presented. Its 10 dB unwanted power rejection improves the tuner performance above 54 dB CNR and 57 dB C/I under loaded spectrum conditions. This filter enables a low-cost high-performance silicon tuner for both analog and digital Set-Top-Boxes and Cable Modems.
