设计了一种基于CMOS多输出第二代电流控制传输器(MOCCCII)的可调谐电流模式双输入、多输出多功能滤波器。该滤波器仅由两个CCCII、一个接地电阻和两个接地电容组成。选择输出端中的一个或它们的组合,即可实现低通、带通、高通、带阻和全通5种二阶滤波功能。电路结构简单,且固有频率oω和品质因数Q可独立调节;具有较低的有源和无源灵敏度。HSPICE仿真结果表明,设计的电路是正确的。 A tunable current mode dual-input multi-output multi-function filter based on CMOS multiple output second generation current control transmitter (MOCCCII) is designed. The filter consists of only two CCCIIs, a ground resistor and two ground capacitors. Select one of the output or a combination of them to achieve low-pass, band-pass, high-pass, band-stop and all-pass five kinds of second-order filtering. The circuit structure is simple, and the natural frequency oω and quality factor Q can be independently adjusted; has low active and passive sensitivity. HSPICE simulation results show that the design of the circuit is correct.
