Simulative development of the electronic component of Mössbauer spectroscopy with a focus on the controllability of a 2nd order transimpedance amplifier

In light-processing systems, light energy is converted into a photocurrent due to the photoelectric effect. This project focuses on the development of a high-precision energy-to-voltage conversion technique to optimize signal processing in light-processing systems, specifically for applications in space analytics or solid state physikcs, such as Mössbauer spectroscopy. Analog circuit development plays a vital role as downstream voltage conversion is necessary for signal processing. The objective is to enhance the signal quality and improve the signal-to-noise ratio through the design, optimization, and comparison of various circuits for voltage conversion. The development process involves the design and optimization of amplifier circuits, supplemented with the incorporation of filters and/or regulators for further improvement. A transimpedance amplifier is approximated as a second-order low-pass filter, while a state controller is designed and analyzed to efficient transient oscillation of the system towards optimal amplitude values for subsequent signal processing. The project's results contribute to the advancement of light-processing systems, enabling more precise analysis of light energy in Mössbauer spectroscopy. The findings are presented in a series of scientific publications, showcasing the effectiveness of the developed circuits and their impact on signal quality. Future work could focus on further optimization and validation of the circuits in real-world applications to confirm their performance and reliability. Overall, this project emphasizes the significance of meticulous circuit development and optimization for enhancing signal processing in light-processing systems, thus supporting their application in space analytics.
