| Abstract: | A novel configuration Of fully differential continuous-time voltage-mode CMOS OTA-C biquad filter employing SFG(signal now graph) is proPOsed and various kinds of differential biquadratic filters are generated systematically .The POle quality factors and pole frequency sensitivities are studied for the proposed filters. The computer simulation at the MOS transistor level is carried out and the results show that the proposed circuits are effective and suitable for fully integration. |
| Keywords: | Fully differential Continuous-time Active filters Fully integration. |
