基于通用集成运算放大器,利用MASON公式设计了一个多功能二阶通用滤波器,能同时或分别实现低通、高通和带通滤波,也能设计成一个正交振荡器。电路的极点频率和品质因数能够独立、精确地调节。电路使用4个集成运放、2个电容和11个电阻,所有集成运放的反相端虚地。利用计算机仿真电路的通用滤波功能、极点频率和品质因数的独立控制和正交正弦振荡,从而证明该滤波器正确有效。 Abstract: A new multifunctional second-order filter based on OPs was presented by MASON formula. Functions, such as high-pass, band-pass, low-pass filtering, can be realized respectively and simultaneously, and can become a quadrature oscillator by modifying resistance ratio. Its pole angular frequency and quality factor can be tuned accurately and independently. The circuit presented contains four OPs, two capacitors, and eleven resistances, and inverting input of all OPs is virtual ground. Its general filtering, the independent control of pole frequency and quality factor and quadrature sinusoidal oscillation were simulated by computer, and the result shows that the presented circuit is valid and effective.
