In this work, a balun low-noise amplifier (LNA) is designed and implemented in 0.18-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, P1dB and IIP3 are 10 dBm and 0 dBm, respectively. The LNA core circuit dissipates 7.32 mW from 1.8 V power supply.
