Rajat Thakur , School of Engineering & Technology, HNB Garhwal University, IndiaAbstract
Signal processing circuits are fundamental components in a wide range of electronic systems, including communications, audio processing, and instrumentation. The performance of these circuits heavily depends on the characteristics of the operational transconductance amplifier (OTA) used within them. This study presents a comprehensive approach to the design and optimization of signal processing circuits utilizing telescopic OTA architecture. The telescopic OTA is chosen for its high gain, low noise, and improved linearity, which are crucial for achieving high-performance signal processing.
The research begins with a detailed analysis of the telescopic OTA's design principles, focusing on its advantages and limitations compared to other OTA architectures. Key design parameters such as gain, bandwidth, and power consumption are examined, and optimization techniques are applied to enhance these parameters. The study includes simulation and experimental validation of various signal processing circuits designed with telescopic OTA, demonstrating the circuit's effectiveness in achieving superior performance metrics.
Optimization strategies are explored to address challenges such as noise reduction, power efficiency, and frequency response. The results highlight significant improvements in signal fidelity, noise performance, and overall circuit efficiency. The study also discusses the practical implications of integrating telescopic OTA into real-world applications, including considerations for design trade-offs and implementation challenges. In summary, this research provides valuable insights into the design and optimization of signal processing circuits using telescopic OTA technology, offering a pathway to achieving high-performance, reliable, and efficient signal processing solutions.
