The TT filter is a basic building block in many analog signal processing applications. Genetic algorithm applications in analog design circuits play an important role with promising results. This paper introduces the TT_GA Technique. It is an intelligent technique for generating equivalent TT Circuits using genetic algorithm realization with Nullor and Pathological elements. The goal is to generate equivalent Second Generation Current Conveyor (CCII) as well as equivalent Transconductance Amplifier (TA) circuits. This Technique generates 8 different TT circuits using CCII circuits. Also, it generates 16 circuits using TA. Some of thegenerated TTcircuits and the conventional op-amp realized filtersare simulated using SPICEand compared to each other’s.A standard CMOS model of 0.25 μm is used.By applying the TT_GA Technique we can get all possible solutions programmatically.
