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.

 本系统基于 C8051F020 实现等精度的频率测量， 利用该单片机灵活的控制功能及速 度优势，大大提高了性能和测量精度。以往的测频都是采用高频段直接计数、低频段间接测周 的方法，其测量精度往往会随着被测频率的改变而受到影响。为了克服测频中高低频段测量精 度不等的缺陷，采用双计数器设计，实现等精度的频率测量。等精度的测量方法不但具有较高 的测量精度，而且在整个测频区域内保持恒定的测量精度。
