This paper presents an inductorless complementary-noise-canceling LNA(CNCLNA) for TV tuners.The CNCLNA exploits single-to-differential topology,which consists of a common gate stage and a common source stage. The complementary topology can save power and improve the noise figure.Linearity is also enhanced by employing a multiple gated transistors technique.The chip is implemented in SMIC 0.18μm CMOS technology.Measurement shows that the proposed CNCLNA achieves 13.5-16 dB voltage gain from 50 to 860 MHz,the noise figure is below 4.5 dB and has a minimum value of 2.9 dB,and the best P_(ldB)is -7.5 dBm at 860 MHz.The core consumes 6 mA current with a supply voltage of 1.8 V,while the core area is only 0.2×0.2 mm~2.
