基于通用集成運(yùn)算放大器，利用MASON公式設(shè)計(jì)了一個多功能二階通用濾波器，能同時或分別實(shí)現(xiàn)低通、高通和帶通濾波，也能設(shè)計(jì)成一個正交振蕩器。電路的極點(diǎn)頻率和品質(zhì)因數(shù)能夠獨(dú)立、精確地調(diào)節(jié)。電路使用4個集成運(yùn)放、2個電容和11個電阻，所有集成運(yùn)放的反相端虛地。利用計(jì)算機(jī)仿真電路的通用濾波功能、極點(diǎn)頻率和品質(zhì)因數(shù)的獨(dú)立控制和正交正弦振蕩，從而證明該濾波器正確有效。 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.
