A Broadband Receive Chain in 65nm CMOS

A fully integrated 65nm CMOS broadband RX front-end using a double-loop transformer-feedback LNA is presented. The frequency band from 2 to 8GHz is covered while the NF remains between 4.5 and 5.5dB and IIP3 is -7dBm. The active die area is 0.09mm 2 and the circuit consumes 51 mW from a 1.2V supply
