JSSC05Dec_Song_TVtunerIEEE JOURNAL OF SOLID-STATE CIRCUITS, VOL. 40, NO. 12, DECEMBER 20052525A CMOS TV Tuner/Demodulator IC With Digital Image RejectionChun-Huat Heng, Member, IEEE, Manoj Gupta, Member, IEEE, Sang-Hoon Lee, Member, IEEE, David Kang, Member, IEEE, and Bang-Sup Song, Fellow Member, IEEEAbstract―Superheterodyne TV tuners have been implemented in discrete forms using tunable RF and SAW IF lters. Integrating TV tuners in CMOS technology without them is a challenging task to cope with technical issues such as harmonic mixing and image. The image rejection in low- or zero-IF systems has been limited to path gain and phase 30……
