Abstract
In the paper we present a 5.7 GHz gain-variable LNA. This LNA is designed in TSMC CMOS 0.18-mum technology based on an improved current-reused cascade common source topology. High gain and low power is achieved. The variable gain range is from 20.73 to 14.6 dB. The LNA achieves 20.73 dB gain, 3.08 dB noise figure, 3 dBm IIP3, and -36.32 dB input return loss at lower gain.
