Abstract

An ultra wideband (UWB) noise-cancelling low-noise amplifier (NCLNA) is proposed in this paper. A common-gate input stage with an input matching network is implemented to make input resistance matching to 50-ohm. The power consumption of the presented NCLNA can be lower by using current-reuse architecture. A noise cancelling technique is adopted to decrease the noise generated by the first common-gate stage. The designed NCLNA is implemented in 180 nm CMOS technology. The simulated results show that the noise figure is among 2.65–3.45 dB within the full bandwidth of 3.1–10.6 GHz. The maximum gain is 15.33 dB in the desired UWB band. Both the input and output reflection coefficients are below −10 dB. The linearity IIP3 is −5.5 dBm at 6 GHz. The core circuit consumption is 9.13mW under a 1.3 V supply voltage.
