提出了一种由MOCCII实现的单输入多输出n阶多功能滤波电路。该电路只需用n个MOCCII、电容和电阻,适当选定输入输出端,可以实现n阶高通、低通、带通和带阻滤波功能。本文所提出的电路结构简单,所用的电容、电阻均接地,易于集成。PIPISE仿真结果进一步证明了理论分析的正确性。 A single-input multi-output n-order multi-functional filter circuit realized by MOCCII is proposed. This circuit only needs n pieces of MOCCII, electric capacity and resistance, the appropriate selection of input and output end, can realize n order high pass, low pass, band pass and band stop filtering function. The proposed circuit structure is simple, the capacitors used, resistors are grounded, easy to integrate. PIPISE simulation results further prove the correctness of the theoretical analysis.
