Abstract
In this paper, a transformer coupled noise cancellation technique for subthreshold Ultra Wide Band (UWB) Low Noise Amplifier (LNA) is presented. This introduces a novel noise cancellation technique with current reuse topology and transformer coupling for better noise and gain performance. Moreover power consumption is considerably reduced by biasing both (two) stages in subthreshold region. This circuit is designed in UMC180nm process and simulated using SpectreRF simulator. This circuit achieved a maximum gain of 14dB and noise figure of 3.6dB over the 3dB bandwidth of 2.4-6GHz. This consumes 1.48mW of DC power from 1.5V supply. Hence the proposed circuit is very useful for WSN applications in ISM (2.4GHz) band and Ultra Wide Band (UWB) group I & II.
