N2  -  <p>The Low Noise Amplifier (LNA) stands as a crucial element RF receiver chain, demanding a delicate interplay of characteristics such as high gain, low noise figure (NF), superior linearity, and an extensive dynamic range. De-signing an ultrawideband (UWB) LNA poses a complex challenge as engineers grapple with intricate trade-offs inherent in these parameters. To address these challenges, noise cancellation techniques have emerged as valuable tools, revolutionizing the design of UWB LNAs by relaxing the traditional trade-off between bandwidth and input matching. This innovative approach not only enhances bandwidth but also effectively cancels out the un-desirable noise and nonlinearities from the input MOSFET. Despite the advancements afforded by noise cancellation, the broad bandwidth of UWB LNAs presents a significant hurdle. If the linearity is insufficient, the UWB LNA faces performance degradation due to increase in-band interference. In response, this article proposes an inventive linearization technique, a combination of Noise Cancelling (NC) and complementary derivative super-position (CDS), aiming to increase the linearity of UWB LNAs. Through meticulous simulations conducted using Cadence Virtuoso with GPDK090 library, the proposed LNA showcases impressive performance metrics across the UWB spectrum. Notably, it achieves a gain ranging from 12.5 dB to 15.5 dB, a noise figure within the range of 3.9 dB to 5.26 dB, and an IIP3 spanning from 6.3 dBm to 8.8 dBm. Remarkably, this innovative LNA accomplishes these feats while operating with a modest power consumption of 11.36 mW from a 1.2 V supply. This groundbreaking technique holds promise for significantly enhancing the efficiency and overall performance of UWB LNAs within contemporary RF receiver systems.</p>
