2．4 GHz CMOS低噪声放大器设计
Design of 2.4 GHz CMOS Low-noise Amplifier
摘要
Abstract
In this paper,two narrowband low-noise amplifiers (LNAs)are designed,which can operate in the 2.4 GHz frequency with TSMC 0.18 μm CMOS technology.One of the circuit structures is Cascode structure with current-reuse technique,and the other is folded Cascode structure with forward-body-bias technique.The simulation results of the designed narrowband LNAs show that,in the 2.4 GHz frequency,Cascode LNA consumes 4.9 mW from a 1.5 V DC supply,gain is 23.5 dB,input and output reflection coefficients are -16.9 dB and -16.3 dB,noise figure is 0.72 dB and IIP3 is 3.12 dBm;and the folded Cascode LNA can operate under 0.5 V DC supply,power consumption is 1.83 mW,gain is 23.8 dB,input and output reflection coefficients are -28.2 dB and -24.8 dB,noise figure is 0.62 dB and IIP3 is -7.65 dBm,which is suitable for low voltage and low power applications.关键词
