【摘要】 分析了基于理想运算放大器构建的滤波器性能以及参数选原则。针对理想运算放大器所构建的滤波器模型当运算放大器为非理想器件时所制造出的滤波器响应性能并不理想这一问题。研究了非理想运算放大器构建的滤波器器件参数对响应时间的影响,提出了一种选取其最优参数值以构建所需滤波器的方法,实验结果表明了该方法的有效性。更多还原

【Abstract】 The parameter selection problem of the filter based on an ideal operational amplifier was analyzed.Aiming at the problem that the filter response wasn’t satisfied,when we designed a filter using the model based on an ideal operational amplifier.The response time and device parameters of the filter designed on an non-ideal operational amplifier was studied,and an method which can calculate the optimal parameters of the filter was proposed.The experimental results show the effectiveness of this method.更多还原
