A 0.18-/spl mu/m CMOS LNAs with sub-2 dB NF and low power for Bluetooth applications

A 2.4 GHz low noise amplifier (LNA), intended for use in a Bluetooth receiver, has been designed in a standard 0.18 /spl mu/m in CMOS process. The amplifier provides a forward gain (s21) of about 25 dB with a noise figure of sub-2 dB, while consuming only 16 mW power with a 1.5 V supply. It has a good linearity, with the IIP3 equal to -8 dBm around.
