| Abstract: | 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. |
