Abstract :
Some novel multifunction biquadratic filters, each of which employs two to three operational transconductance amplifiers and two capacitors, are presented. Each proposed circuit offers the following advantageous features: realization of different biquadratic filter signals from the same configuration, no requirements for component-matching conditions, employment of only two capacitors, control of ωo and ωo/Q, with separate tunable transconductances and low sensitivities
