A fully integrated 5 GHz low-power electrostatic discharge (ESD)-protected low-noise amplifier (LNA) in 90 nm CMOS is presented. This 9 mW LNA, with a 1.2 volt supply voltage, features a 12 dB power gain and 3.4 dB noise figure, while maintaining an input return loss below -20 dB. The LNA is ESD protected up to 5.5 kV human body model (HBM) using an on-chip inductor and clamping diodes, implemented as "plug-and-play" components. To the authors' knowledge, this LNA achieves the highest ever-reported ESD protection level in any 90 nm RF CMOS technology.
