A 2.17-dB NF 5-GHz-band monolithic CMOS LNA with 10-mW DC power consumption


Design principles of CMOS low-noise amplifiers (LNAs) for simultaneous input impedance and noise matching by tailoring device size for R/sub opt/=50 /spl Omega/ are introduced. It is found that R/sub opt/ close to 50 /spl Omega/ can be obtained by using small devices (110 /spl mu/m) and small currents (5 mA). Based on the proposed approach, CMOS LNAs with… (More)
