A 3.6 dB NF, 6 GHz band CMOS LNA with 3.6 mW power consumption

This work presents a fully integrated 6 GHz LNA designed using 0.12 mum IBM CMOS technology. The amplifier consumes only 3.6 mW dc power with 1.2 V supply voltage, and features a 11 dB power gain and 3.6 dB noise figure at the frequency of 6 GHz. Additionally, it achieves -11 dBm of input referred 1 dB compression point and -0.5 dBm of IIP3. At the same time input and output matching are better than -15 and -10 dB, respectively. It is shown that capacitance connected between the gate and ground of the common source transistor can be used for improving the performance of the LNA
