CMOS Low Noise Amplifier Topology Using Compact Wu Folded Active Inductor

This work presents a topology proposal of a 0.35um CMOS cascode low noise amplifier using an active inductor. The inductance required to output of cascode pair is synthesized by an active inductor in Compact Wu Folded configuration. The LNA presents a gain of 12.04 dB with a noise figure of 4.78 dB at 1.8 GHz. The layout is presented occupying an active area of 0.165 mm2. The results are satisfactory, validating a compact design and demonstrating the technical feasibility of this topology in the band of interest.
