Design of a Noise-canceling Differential CMOS LNA for 3.1-10.6 GHz UWB Receivers

摘要：

An ultra-wideband (UWB) 3.1-10.6 GHz fully differential low noise amplifier (LNA) employing the broadband noise-canceling technique is presented.With the proposed circuit topology,the noise from the input matching transistor is entirely suppressed over the full UWB band. The LNA is designed in 0.18μm CMOS technology. The simulated results show that the noise figure is 3.7-4.5 dB and the power gain is 13.4-14.1dB in the desired UWB band,both the input and output reflection coefficients are below -10dB,and the iIP3 is -6.3dBm at 5.7 GHz.It consumes 12.5 mW from a 1.8V supply.
