The article focuses on low-noise amplifiers (LNAs). It is stated that multiple communications standards could be served by LNAs by merit of its low noise figure. It is noted that to suppress interference and maintain good receiver sensitivity, high linearity is important in an LNA. It is mentioned that semiconductor process in which all required components can be integrated is the basis of the LNA.

The article reports that a fully integrated differential low-noise amplifier (LNA) has been designed with an interstage LC parallel tank circuit with common-gate (CG) and common-source (CS) transistors. It consumes 34.3 mW from a +1-VDC supply and achieves peak gain of 23.8 dB and minimum noise figure of 3 dB with -3.8 dBm output power.
