【摘要】 通过器件Z参数分析噪声等效电路及计算最小噪声系数 ,利用HPADS软件仿真了等效电路元件对最小噪声系数的影响 ,从而得出了根据器件几何、物理参数来改进器件高频噪声性能的有效途径。
【Abstract】 The minimum noise figure was calculated by using Z parameters analysis. The influence of the equivalent circuit elements on the minimum noise figure was simulated by using HP ADS software. The available method was proposed to improve device high frequency noise performance by changing device′s geometry and physics parameters.
