This paper represents an ultra-wide band low noise amplifier (LNA) that stands out for it high degree of simplicity, small size, extremely low power consumption and impressive broadband performance. Smart choice of topology, device scaling and Active Impedance Matching Technique enabled a good broadband matching off the amplifier. The measured performance featuring 10.2 dB transducer gain with -3 dB bandwidth of 50 GHz, 4.7 dB noise figure and 8.06 mW DC power consumption, yields by far the best figure of merit (FOM) reported up to date.
