基于可编程跨导运算放大器POTA低通有源滤波器设计。该文给出了基于可编程跨导运算放大器(POTA)的有源滤波器设计方法，能在一定范围内实现跨导值程控调节, 提高调节精度和准确度。并且利用Jacobi 法求解相似对角形矩阵，避免解高次方程的难题。所设计的有源滤波电路不易受分布电容的影响，稳定性好、灵敏度低。本文给出了设计实例，显示了该方法的优点。-Based on programmable transconductance operational amplifier POTA low-pass active filter design. In this paper, based on the programmable transconductance amplifier (POTA) of the active filter design method that can realize in a certain range transconductance value of program-controlled adjustment, improve precision and accuracy regulation. Jacobi method and use a similar matrix of angular, high-equation solution to avoid problems. Designed active filter circuit less susceptible to the effects of distributed capacitance, good stability, low sensitivity. In this paper, design examples, showing the advantages of the method.

我想利用本月的专栏描述一个有趣的应用程序，这个程序是用本期我的一篇文章：“使用 ManWrap 库在本机 C++ 代码中调用.NET”所讨论的 RegexWrap 库生成的。RegexForm 是一个基于正则表达式的MFC窗体有效性验证系统。为了实现这个程序，我首先实现了 RegexWrap。但因为许多细节与正则表达式本身无关，所以感觉在这里描述 RegexForm 更好些。-I would like to use this month"s column describes an interesting application procedures, which is a period of my article : "The use of ManWrap Library in the C code for a call.NET "are discussing the formation RegexWrap library. RegexForm is a regular expression is based on the MFC Form Validation System. To achieve this procedure, I realized RegexWrap. But because many details with the expression itself is not, so the feeling here describe RegexForm better.
