| 摘 要： | 设计了一款多用途、宽带、无电感的低噪声放大器。放大器的第1级为单端输入差分输出结构,采用了噪声抵消技术来降低噪声；第2级引入有源感性负载,并通过电阻负反馈来扩展带宽。采用TSMC 130 nm工艺对电路进行仿真,后仿结果表明,在0.4~6.2 GHz带宽范围内,S21为19 dB,噪声系数为1.9~2.5 dB,功耗为9.6 mW,电路核心面积为0.08 mm2。

| Abstract: | A versatile wide band and inductorless low noise amplifier(LNA) was designed. Input of the first stage was single-ended exploiting noise canceling technique while output was differential. To extend the bandwidth, an active inductive load was introduced in the second stage with the help of resistor feedback structure. The circuit was simulated with TSMC 130 nm process. Simulation results showed that S21 was 19 dB in bandwidth of 0.4-6.2 GHz. NF was withen 1.9-2.5 dB. The LNA consumed 9.6 mW and the core area was 0.08 mm2. |
