Abstract

A twostage 25GHz CMOS Low Noise Amplifier(LNA) for the lower side of UltraWideBand(UWB) applications(3.15GHz) is presented. This LNA consists of two stages. The first stage is a commongate structure maintaining good linearity with better input matching; the second stage is a commonsource stage stacked with a current mirror, which obtains low Noise Figure(NF) and reduces the LNA’s power consumption. By introducing commongate and commonsource stages to compensate gain mutually, the proposed LNA has achieved nearly flat power gain and NF. This LNA has been implemented by a 0.18μm CMOS process. The successive simulation results indicate that the power gain(S21) keeps 11.5dB over the wide frequency band of 25GHz with NF 5.1dB and input return loss(S11) below 22dB in the entire band. The simulated inputreferred thirdorder intercept point(IIP3) at 4GHz is 10dBm. The LNA consumes about 11mW under the 1.8V supply.

Key words： low noise amplifier(LNA);ultrawideband(UWB);noise figure(NF);inputreferred thirdorder intercept point(IIP3)
