New Minimum Component Multifunction Active OTA-C-Filter

Wu Jie (Department of Electrical Engineering, Hunan Univ, Changsha, 410082)  
A new active OTA-C biquadratic filter is presented which can realize all standard sec-ond-order responses. The circuit can also simultaneously provide three filtering outputs in a singlestructure by using only three OTAs and two capacitors, the minimum number of components.
