介绍了确定 CMOS运算放大器各级工作点的恒流源偏置电路随辐照总剂量变化的响应特征及其辐照敏感性对运放整体性能参数的影响规律。结果表明 ,恒流源特性的衰降对电参数的变化有一定的影响 ,但在一定范围内并不是造成辐射感生运放电参数衰变的最主要原因
The influence of the response characteristic of the constant current source biasing circuit at various operating points of CMOS operational amplifier with the change of the total radiation dose and the influence of its radiation sensitivity on the overall performance parameters of op amp are introduced. The results show that the decay of the constant current source has certain influence on the change of the electrical parameters, but it is not the most important reason that causes the decay of the parameters of the radiation inducing operational optics within a certain range
