Abstract: This paper comprises a design analysis of a low power (LP) Low noise amplifier (LNA) for UWB applications. Proposed LNA consists of two parallel path, one is the mutually coupled CS stage and second is CG path. The Mutually coupled path in the CS stage is beneficial for improving transconductance as well as input impedance matching. Since CS path provides high power gain and the CG path provides a wide bane matching. A noise cancellation technique is also used to reduce the noise of CG path, thus reducing the overall noise and increasing the gain in the UWB range. The proposed LNA successfully simulated in 90-nm CMOS technology. The results of proposed work indicate optimization (NF) at frequency 7.68 GHz with 3dB bandwidth of 1.4-7.8 GHz. All simulation has been done for a range of frequency 01-11 GHz in Cadence virtuoso software. The results quoted 2.72dB NF at frequency 7.686GHz, -16.389.1dB S11, 12.87dB S21, at frequency 4.8 GHz, maximum GP and GA is 10.26 dB,10.76dB at frequency 9.6GHz, with 1.2V, 1.96mW broad band LNA.
