摘      要：A 9.8–30.1 GHz CMOS low-noise amplifier(LNA)with a 3.2-dB minimum noise figure(NF)is *** the architecture level,a topology based on common-gate(CG)cascading with a common-source(CS)amplifier is proposed for simultaneous wideband input matching and relatively high *** the circuit level,multiple techniques are proposed to improve LNA ***,in the CG stage,loading effect is properly used instead of the conventional feedback technique,to enable simultaneous impedance and noise ***,based on in-depth theoretical analysis,the inductor-and transformer-based gm-boosting techniques are employed for the CG and CS stages,respectively,to enhance the gain and reduce power ***,the floating-body method,which was originally proposed to lower NF in CS amplifiers,is adopted in the CG stage to further reduce *** in a 65-nm CMOS technology,the LNA chip occupies an area of only 0.2 mm^(2)and measures a maximum power gain of 10.9 dB with−3 dB bandwidth from 9.8 to 30.1 *** NF exhibits a minimum value of 3.2 dB at 15 GHz and is below 5.7 dB across the entire *** LNA consumes 15.6 mW from a 1.2-V supply.
