一种24～27 GHz共源共栅高增益低噪声放大器设计
A Design of a 24-27 GHz Cascode High Gain Low Noise Amplifier
摘要
Abstract
Based on a 40 nm CMOS process,a high-gain low noise amplifier(LNA)chip was designed.The topology architecture of the chip adopted transformer input matching technology and positive feedback same-phase amplification technology to improve the input matching degree and gain.By introducing an active biasing network and a transformer matching network into the input stage of the traditional common-source common-gate structure,the chip can not only work stably at room temperature,but also shows excellent performance within the temperature range of-40℃to 125℃in simulation.Therefore,this design can be used for transceiver receiving ports in millimeter wave frequency bands under different temperature environments,and has certain temperature stability characteristics.The chip's layout size is 0.383 mm×0.694 mm.The post-layout simulation results show that the LNA achieves a noise figure of less than 4.96 dB,a maximum gain of 18.11 dB,an input return loss of less than-16.08 dB,and an output return loss of less than-11.54 dB within the working frequency range of 24～27 GHz at room temperature.In addition,the LNA design has excellent performance indicators such as an input P1dB of-20.36 dBm and a DC power dissipation of 12.8 mW.关键词
