A novel continuous-time current-mode biquad filter employing CCIIs

A novel configuration of a CCII-based continuous-time current-mode biquad filter is proposed in this paper. The filter is only made of minim CCII elements and grounded resistors and capacitors; the topology is really simple and the performance is really good, so it is suited for full integration. A computer simulation is carried out and the results show that the proposed circuits are effective.
