RF receiver front-end with +3dBm out-of-band IIP3 and 3.4dB NF in 45nm CMOS for 3G and beyond


A receiver front-end in standard 45 nm CMOS technology is presented. The receiver achieves WCDMA system performance without requirement for an inter-stage SAW filter. High out-of-band linearity performance is achieved by reducing the RF circuitry and filtering the out-of-band blockers after direct conversion. For the receiver at 1.9 GHz, a +3.1 dBm IIP3 is… (More)
