An adaptive sampler using the IF-TEM method. This method allows for low-energy, asynchronous sampling by sampling only when the input signal changes. The project involves circuit design, PCB integration, and system validation through testing.
The project revolves around developing an adaptive sampler based on the IF-TEM (Integrate and Fire Time Encoding Machine) approach. The method leverages asynchronous sampling for low energy consumption and precise data acquisition by sampling only when changes occur in the input signal. The project involved the meticulous design of the electronic circuit, divided into analog and digital sections, with key components selected for their application suitability. The design was then embedded on a PCB (Printed Circuit Board), which included creating a schematic using CAD software, laying out the PCB for optimal component placement, and ensuring proper electrical connections. The analog section processed the signals while the digital section, including the ESP32 microcontroller, managed data processing and control logic. Programming the ESP32 and conducting rigorous testing validated the system’s performance and reliability. The project’s implementation demonstrates the feasibility of using the IF-TEM method in energy-critical applications like portable and wireless devices.
