【摘要】：为了在不增加功耗的前提下提高低噪声放大器的增益,本文通过引入电流复用技术,并将偏置管兼作放大管,设计出一款全集成高增益低功耗超宽带低噪声放大器。采用TSMC公司的0.18μm CMOS工艺和Cadence软件对本低噪声放大器电路进行前仿真和后仿真。仿真结果表明,在1.5V的电压供电下,整个电路的功耗(power consumption,PD)为11.7mW,在2.8~8.5GHz的频段内,噪声系数(noise figure,NF)为3.05~4.1dB,正向增益(S21)为18.2~19.9dB,输入回波损耗(S11)、输出回波损耗(S22)均小于-10dB,群延迟为130~320ps,在6GHz处,三阶交调点IIP3为-12.16dBm,达到了设计目标。该低噪声放大器具有高增益低功耗的特点,可用于对增益和功耗要求都较高的接收机中。
[Abstract]:In order to improve the gain of LNA without increasing power consumption, a fully integrated UWB low noise amplifier with high gain and low power consumption is designed by introducing current multiplexing technology and using bias transistor as amplifier. The TSMC 0.18 渭 m CMOS process and Cadence software are used to simulate the low noise amplifier circuit before and after. The simulation results show that the power consumption (power consumption,PD) of the whole circuit is 11.7mW under the voltage supply of 1.5V, and the noise coefficient (noise figure,NF) is 3.05n4.1dBin the frequency band of 2.8~8.5GHz. The forward gain (S21) is 18.2um 19.9dB, the input echo loss (S11) and the output echo loss (S22) are all less than -10dB, and the group delay is 130 ~ 320ps. At 6GHz, the third-order crossover point IIP3 is -12.16dBm. the design goal is achieved. The LNA has the characteristics of high gain and low power consumption and can be used in receivers with high gain and high power consumption.
