History and Progress of the Tow Thomas Bi-Quadratic Filter Part III: Generation Using NAM Expansion
نویسنده
چکیده
A new generation method of the Tow-Thomas (TT) circuit based on the nodal admittance matrix (NAM) expansion is given. The family of TT circuits de ̄ned includes four di®erent types of generated circuits. All the advantages of the classical TT circuit namely, independent control on the frequency, selectivity factor Q and gain, besides having very low passive sensitivities are maintained. Besides, each of the family members of the generated circuits use grounded passive elements and has very high input impedance. It is found that there are eight circuits in each type implying a total of 32 TT circuits using current conveyors (CCII) and inverting current conveyors (ICCII). 24 circuits are new and four of them have a °oating property.
