摘要
提出了一种采用电流控制传送器(CCCⅡ)构成的连续时间双二阶滤波器电路,该滤波器可以应用于助听器和其他的信号处理设备中,能对任意特定频率的信号进行放大或者衰减,易于实现大规模MOS电路的集成。理论分析和计算机仿真表明所提电路方案正确,是可行的。
In this paper, a continuous-time biquadratic filter using Current Controlled Conveyors （CCCII） is proposed, which can be used in Hearing Aids and in other Analog Signal Processing applications. The proposed filter has the capability of amplifying as well attenuating the signal of any desired frequency band. This design can be easily implemented in MOS VLSI thereby allowing electronic tuning of the filter parameters. Theoretical analysis and computer simulation indicate that the proposed circuit is effective and feasible.
