| Summary: | This work details the optimization and evaluation of a CMOS low-noise amplifier by developing a new algorithm for the <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mrow><msub><mi>g</mi><mi>m</mi></msub><mo>/</mo><msub><mi>I</mi><mi>D</mi></msub></mrow></semantics></math></inline-formula> approach and combining with a modified figure of merit index method. The amplifier includes on-chip matching elements (such as IC inductors) for resonance at the targeted frequencies. The simulation results of the optimized LNA model showed scattering parameter <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><msub><mi>S</mi><mn>21</mn></msub></semantics></math></inline-formula> = 19.91 dB, noise figure NF = 3.54 dB and excellent linearity for third-order intermodulation parameter IIP3 = 5.89 dBm for the targeted frequency of <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><msub><mi>f</mi><mn>0</mn></msub></semantics></math></inline-formula> = 2.4 GHz. |
