This paper presents an optimized approach to designing OTA-C filters with a focus on reducing the number of components while maintaining or improving performance. By employing shared sub-blocks within the transconductance amplifier architecture, the proposed method minimizes power consumption and circuit area, ensuring efficient integration in modern electronic systems. The paper also discusses the theoretical basis for the design, implementation details, and performance evaluation of the optimized filters. The results demonstrate significant improvements in resource efficiency and scalability compared to conventional designs.
