Abstract
A tuner includes a plurality of paths, and at least one of the paths includes a front-end filter circuit, an amplifier, and a trace filter. The trace filter includes a varactor and an inductor, which are coupled to an output end of the amplifier. Further, the amplifier and the varactor of the tuner are packed in a complementary metal-oxide semiconductor (CMOS) chip.
