A 1.2 V 114 mW Dual-Band Direct-Conversion DVB-H Tuner in 0.13 $\mu$m CMOS

A fully integrated direct-conversion tuner is implemented in 0.13 $\mu\hbox{m}$ CMOS technology. A broadband noise-canceling balun LNA with the proposed dual cross-coupling technique helps achieve an overall receiver noise figure from 3.7 to 4.3 dB while consuming only 3.6 mW. The proposed current-mode switching scheme improves the achievable SNIR with a gain step of 15 dB, providing IIP3 improvement of 18 dB and NF degradation of only 6 dB. …
