抄録

In this paper, a highly linear and low noise CMOS active RF tracking filter for a digital TV tuner is presented. The <i>G<sub>m</sub></i> cell of the <i>G<sub>m</sub></i>-<i>C</i> filter is based on a dynamic source degenerated differential pair with an optimized transistor size ratio, thereby providing good linearity and high-frequency operation. The proposed RF tracking filter architecture includes two complementary parallel paths, which provide harmonic rejection in the low band and unwanted signal rejection in the high band. The fabricated tracking filter based on a 0.13µm CMOS process shows a 48∼860MHz tracking range with 30-32dB 3rd order harmonic rejection, a minimum input referred noise density of 2.4nV/√Hz, and a maximum IIP3 of 0dBm at 3dB gain while drawing 39mA from a 1.2-V supply. The total chip area is 1mm × 0.9mm.
