| Abstract: | An ultra-wideband low noise amplifier with cascode structure is presented in this paper.This circuit,based on TSMC 0.18 μm CMOS technology,operating from 3 GHz to 5 GHz,is used to realize ultra-wideband radio.The simulation results indicate that the low noise amplifier provides a maximum gain of 13.6 dB, and noise figure of the whole spectrum is smaller than 1.9 dB. The input and output return losses are below-11 dB. The 1 dB compression point is about -15 dBm,and the power consumption is 18.7 mW. |
