An Ultra-Wideband Common Gate LNA With Gm-Boosted And Noise Canceling Techniques
Journal Title: Journal of Information Systems and Telecommunication - Year 2014, Vol 2, Issue 2
Abstract
In this paper, an ultra-wideband (UWB) common gate low-noise amplifier (LNA) with gm-boosted and noise-cancelling techniques is presented. In this scheme we utilize gm-boosted stage for cancelling the noise of matching device. The bandwidth extension and flat gain are achieved by using of series and shunt peaking techniques. Simulated in .13 um Cmos technology, the proposed LNA achieved 2.38-3.4dB NF and S11 less than -11dB in the 3.1-10.6 GHz band. Maximum power gain (S21) is 11dB and -3dB bandwidth is 1 .25-11.33 GHz. The power consumption of LNA is 5.8mW.
