Researchment and Design of CMOS Low Noise Amplifier in UHF Band

摘要：

To overcome difficulties among power,noise figure(NF) and matchInthe design of low-noise amplifier(LNA),a novel approach that can realize effective compromise among them is presented through analyzing the cascade LNA configuration. Under the premise that power can be accepted,the new approach can be achieved by adopting series inductors ininput port,adding capacitors between gate and source nodes and appending series inductor-resistance to the output port.Experimental results show that,with the proposed approach,a 0.18pro CMOS LNA at 2.4 GHz could provideA maximum NF of 0.46 dB,a minimum power gain of 22 dBIn3 dB bandwidth,input and output VSWRs which are better than 1.12,the output P1dB power of 1.07dBm and 25.02 mW whole power consume.Theory analysis agrees well with the simulation results.
