摘要
基于SMIC 0.18μm CMOS工艺,采用可重构结构,设计了一种应用于北斗、GPS导航系统接收机的可切换双频段低噪声放大器。采用Cadence Spectre RF仿真器进行仿真和验证。结果表明,在1.2GHz频段,该放大器的增益为17.6dB,噪声系数为2.8dB,S_(11)为-11.1dB,S_(22)为-11.3dB;在1.57GHz频段,该放大器的增益为15.1dB,噪声系数为2.98dB,S_(11)为-11.7dB,S_(22)为-10.6dB。芯片尺寸仅为1 260μm×844μm。在1.8 V供电电压下,直流功耗仅为28.8mW。
A switchable dual-band reconfigurable low noise amplifier(LNA)was designed in the SMIC 0.18μm CMOS process for the navigation system receiver of BDS and GPS.The simulation and verification of LNA were completed by the Cadence Spectre RF simulator.The post-simulation results showed that the LNA had a gain of 17.6 dB,a noise figure of 2.8 dB,an input reflection coefficientS11of -11.1 dB,and an output reflection coefficientS22of -11.3 dB at a frequency of 1.2 GHz.At a frequency of 1.57 GHz,the LNA had a gain of 15.1 dB,a noise figure of 2.98 dB,an input reflection coefficient(S11)of -11.7 dB,and an output reflection coefficientS22of -10.6 dB.The chip area was 1 260μm×844μm,and the static power consumption was only 28.8 mW at 1.8 Vsupply voltage.
