中文摘要:为了验证电路的可靠性,对InP异质结双极晶体管的微波特性进行了基于蒙特卡洛方法的波动分析。器件微波特性的波动程度不同,波动范围越大说明对本征参数的提取精度要求越高,可以通过输出特性推断测量可允许的精度范围。微波特性由模型S参数、电流增益截止频率和最大振荡频率组成,根据π型拓扑结构小信号模型本征参数的不确定度曲线,可以导出蒙特卡洛数值分析所需的标准差。蒙特卡洛分析结果表明,在不同的频率不同的偏置条件下,对测量参数准确性的要求差异较大,验证了电路在不同情况下的可靠性。

Accuracy Estimation of Microwave Performance for InP HBTs based on Monte-Carlo Analysis
Abstract:In order to verify the reliability of the circuit, the microwave performance for InP HBTs is analyzed based on Monte-Carlo method. The larger the fluctuation range is, the higher the accuracy of extracting intrinsic parameters is required. The allowable accuracy range can be inferred from the output performance. The microwave characteristics are composed of modeled S-parameters, current gain cut-off frequency and maximum oscillation frequency. The standard deviation of Monte-Carlo numerical analysis can be derived from the uncertainty curve of the intrinsic parameters of the π-topology small signal model. The results of Monte-Carlo analysis show that the requirements for the accuracy of measurement parameters are quite different under different frequency and bias conditions, which verifies the reliability of the circuit under different conditions.
