A two stage cascode low noise amplifier using tapered inductors with optimized quality factors was designed in a 130 nm logic CMOS process. The K-band (24 GHz-26.5 GHz) LNA consumes 11.25 mW DC power for a supply voltage of 1.5 V, achieves 27.5 dB peak transducer gain and 3.88 dB noise figure (NF) at 25 GHz. S11 and S22 at 25 GHz are −13 dB and −10 dB, respectively. It achieves a minimum NF of 3.5 dB at 24 GHz and within the entire frequency band of interest the NF is less than 5 dB. IIP3 of the LNA is −11 dBm and the LNA including pads occupies an area of 830μm × 800μm.
