【摘要】：设计一种满足全频段全球卫星导航系统(global navigation satellite system,GNSS)接收机应用要求的低噪声放大器(low noise amplifier,LNA)。为提高射频前端的集成度并降低成本,提出一种基于发射极电感负反馈结构宽带LNA的实现方法,并对电路结构、宽带输入阻抗匹配和噪声性能进行分析。电路采用0.18μm SiGe BiCMOS工艺设计和实现。研究结果表明:在GNSS全频段范围(1 164~1 610 MHz)内,输入回损大于8.0 dB,输出回损大于8.9 dB,噪声系数低于1.30 dB,功率增益高于14.9 dB,输入三阶互调点为-5.8 dBm。芯片最低功耗为9.6 mW,面积约为600μm×650μm。
[Abstract]:A low noise amplifier (LNA), low noise Amplifier (LNA), is designed to meet the requirements of global navigation satellite system (GNSS) receiver. In order to improve the integration of RF front-end and reduce the cost, a low noise amplifier (LNA) is designed. A method of realizing wideband LNA based on emitter inductor negative feedback structure is presented. Wideband input impedance matching and noise performance are analyzed. The circuit is designed and implemented using 0.18 渭 m SiGe BiCMOS process. The results show that: in the full frequency range of GNSS (1164 MHz), The input back loss is more than 8.0 dB, the output return loss is greater than 8.9 dB, the noise coefficient is less than 1.30 dB, the power gain is higher than 14.9 dB, the input third-order Intermodulation point is -5.8 dBm.The minimum power consumption of the chip is 9.6 MW and the area is about 600 渭 m 脳 650 渭 m.
