A 65nm CMOS multi-standard, multi-band mobile TV tuner

A direct conversion, 65 nm CMOS multi-standard TV tuner is presented, which is compliant with several digital terrestrial, fixed and mobile TV standards (DVB-T, DVB-H, T-DMB and ISDB-T, including 1-3 segment). The tuner achieves a 3/3/2.8 dB NF at VHF, UHF and L-band respectively, while consuming less than 140 mW in DVB-T mode. By using integrated transformers, both single-ended and differential RF inputs are supported. Multi-standard capability is enabled by programmable channel-select filters and a Sigma-Delta fractional-N synthesizer.
