Abstract
This paper presents a highly linear wideband low-noise amplifier (LNA) adopting the current amplification and distortion cancellation, it exploits the noise cancellation for the low-noise, and employs a low second-order distortion PMOS/NMOS input pair and the current mirror amplifier in order to highly improve the linearity. The proposed CMOS LNA exhibits a power gain of 16.0 dB, an IIP3 of 9.5 dBm, and an average noise figure of 2.9 dB with 24.4 mW power consumption at a 1.8 V power supply. The LNA was designed in a 0.18-?m RF CMOS process.
