    In this work, a balun low-noise amplifier (LNA) is designed and implemented in 0.18-mu m CMOS process. The bulk cross-coupling (BCC) and capacitance cross-coupling (CCC) techniques are introduced in this LNA, which not only increase gain and linearity but also decrease noise figure. The 3 dB bandwidth extends from 1.27 GHz to 5.31 GHz. The maximum differential gain is 10.13 dB. Measured at 3 GHz, P-1dB and IIP3 are -10 dBm and 0 dBm, respectively. The LNA core circuit dissipates 7.32 mW from 1.8 V power supply.

    A fully integrated direct-conversion tuner is implemented in 0.13 mu 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. Moreover, design trade-offs are carefully considered in designing the baseband circuit, which provides wide gain tuning and bandwidth accuracy with a DC offset residual less than 6 mV. The measured maximum SNR values are better than 30 dB over wide input power levels, ensuring robust reception in a mobile environment. All circuit blocks are operated at 1.2 V. As a result, the tuner consumes power as low as 114 mW in the continuous mode. This compact tuner supports both UHF and L-bands, and occupies only 7.2 mm(2) die area.
