<p>The current research paper presents a design of a mutually coupled cascode Common Gate Common Source (CG-CS) Low Noise Amplifier (LNA) using current reuse technique. The proposed design provides a significant improvement in the gain and noise performance of the LNA, while also reducing power consumption. Mutually coupled inductors help in reducing the size of the circuit while transformer connected at the output provide output impedance matching. Proposed LNA simulated for the 4–14 GHz RF frequency. Mathematical analysis of proposed LNA has been analyzed using the small signal model henceforth input impedance; gain and Noise Figure (NF) have been derived from it. The design and simulation results show that the proposed LNA design with current reuse technique achieved a maximum gain of 17.87 dB, minimum NF of 5.45 dB, and input reflection coefficient less than –10 dB for the 10 GHz bandwidth. These results indicate a significant improvement in the overall performance of the LNA compared to conventional designs as Figure of Merit (FoM) is 17.34.</p>
